CCD, the full name is Charge Coupled Device, translated as charge coupled device, this technology was invented in 1969 by Bell Labs in the United States, when two famous scientists, Willard Boyle and George Smith, designed a device that can transfer charge along the surface of a semiconductor, and then found that this device can sense the change of light and form an image.

This is a great discovery, after all, before that, only film could get pictures by means of light sensitivity, and as long as they were focused, the image could be captured clearly, and there was no such thing as resolution, which was very clear.

However, the film has a significant flaw: it cannot transmit images in real time, and it needs to be washed out in a dark room after the entire film is used up.

Reconnaissance satellites traveling in space need to launch a package back to the ground every once in a while, which is filled with used film, and then handed over to ground analysts, as well as telescopes to observe outer space, and the photos taken have to be sent back, astronomers are miserable about this, so after the emergence of this CCD technology, they immediately fell in love with it and wanted to use it on space telescopes.

One of the strange things about Bell Labs is that it researches a lot of advanced technologies, but a lot of them are not commercialized, and this depends on other companies.

After the advent of CCD technology, Fairchild was very interested and began to study vigorously, in 73 years, the world's first commercial CCD image sensor was manufactured, and in 75 years, Keda Company used the Fairchild 201100 CCD produced by Fairchild to manufacture the world's first digital camera, which has since entered the digital age. At this point, it only has a pitiful 100*100 resolution.

It's a pity that the digital camera was invented by Keda, but they didn't pay attention to it, for fear that the technology would develop too fast and make them lose the film market.

Although it is only 89 years and digital cameras have not yet been rolled out in large quantities, there are already many companies that are tinkering with it, especially Fujifilm.

In 1988, Fujifilm unveiled the new Fujix DS-1P camera at the World Image Exposition in Cologne, Germany, which not only reached 400,000 pixels, but also had a removable solid-state memory card developed in collaboration with Toshiba.

And now, the drone in Qin Feng's hand is equipped with this camera, and it also has the functions of autofocus and automatic photography.

In this era, there are no small cameras, and there is no high-speed data transmission channel, so the drone can only carry the digital camera to the sky first, take a good photo, and then come back to check, fortunately, the digital camera is available, otherwise the drone really has no practical value.

Xu Dashou watched Qin Feng operate in surprise, until the four rotors of the drone flew away with a buzzing sound, and his eyes moved with the drone, his eyes full of shock.

"Mr. Qin, what is this?"

"Quadcopter UAV, the high-tech product of our Pacific Group." Qin Feng replied.

With a digital camera, this drone has a practical value, for example, now, it can help to find the way ahead!

At this time, Xing Fuqiang had already reacted: "That's right, as long as you fly from above, you can know which road is easy to go, and then we can choose the most suitable route, so we don't have to bump around like headless flies!" However, Mr. Qin, let's go to the national shooting range for testing, why do we still have this thing with us? ”

In fact, it's nothing, but I just want to show off to the leaders of the troops, but I didn't expect it to come in handy at this time!

Last night, when Qin Feng decided to send Sha Lihai to the hospital, he had actually thought that he was going to leave like this, others didn't dare to leave, we have no problem, because we have a trick!

"This drone, you don't need to control it?" Xu Dashou was shocked again, this drone is very flexible in the air, not only flying in a straight line, but also turning, and in the process of turning, he didn't see Qin Feng's operation!

"Yes, I have already preset the program, shoot all the places where we are 20 kilometers square, and fly back after shooting, we can analyze it on the computer and determine the best route!"

Of course, the photos taken by the digital camera need to be analyzed on the computer, after all, the computer screen is still relatively large.

"Computer?" Xu Dashou continued to be surprised, watching Qin Feng open the other boxes, and then really put out a computer.

This computer is actually intended to be displayed after going to the shooting range, after all, the photos taken by the drone have to be released from the computer, but I didn't expect that it can be used now.

Although there were already notebooks in the eighties, the notebooks of this era were all big boxes, the display was still super small, and there was no practical value, even if the Loongson No. 1 was advanced enough, it couldn't stand the LCD screen, so Qin Feng didn't tinker with any laptops, and what he brought directly was a desktop.

I put the computer directly away, and then connected to the on-board power supply, and went through the motor-generator conversion halfway, but fortunately this set of equipment was brought together.

The drone flew back after half an hour, Qin Feng pulled out the memory card inside, plugged in the card reader, entered the computer, and soon, a graphic appeared on the screen.

"Come, let's plan together, plan it out, mark the route on the map."

Half an hour later, the big eight rounds started again, and this time, Xing Fuqiang was full of confidence.

"Don't worry, Mr. Qin, we will definitely be the first to arrive this time! There are only two big rocks to climb along the way, and our car has enough power! Xing Fuqiang said proudly while driving.

There were rocks everywhere, and there was simply no way out, but after aerial reconnaissance, they found a suitable route!

The engine was roaring, the thick off-road tires were crushing the ground, and it looked like there was no way in front of him, but when he got to the front, it was a peak and a loop, looking at all this, Xu Dashou was full of emotion.

"I've heard before that the Pacific Group is amazing, Mr. Qin is very powerful, and this time I finally saw it, anything that is impossible with you can become possible."

"That's the power of technology." Qin Feng said: "Science has turned us into giants, Director Xing, drive another thirty meters ahead, turn right, and get on that big stone!" ”

Look at the videos of those off-road players, there is obviously a road next to it, but if you don't go, you have to walk on big rocks, those modified bigfoot monsters can climb on the stones, they will cheer, if they fall or even overturn, they will also climb out of it, with smiles on their faces, playing.

It's not a game now, it's a mission, but the passability of the big eight rounds is much better than those of the Wrangler modified by the player.

The front wheel of the big eight wheels first touched the stone, and then Xing Fuqiang stepped on the accelerator, and the front wheel climbed on the stone, leaving two black marks on it, and then, the middle two rows of tires were suspended, leaving only the front and rear tires to exert force.

At this moment, there was a rumbling sound in the sky.

Two air jumpers arrived!

There is only the pilot in front, and the back seat is empty, so it is convenient to take people back, in case the car is stuck here, people go back first.

Pilot Zhang Cheng wore sunglasses and was heroic, and he flew while looking down.

Pilot Wang Hu still had some complaints.

"How is this possible, there are no vehicles that can walk through this pile of rubble, the superiors don't know what they are thinking, let us look for it here."

"It's impossible for others, but that Mr. Qin, he can do anything, Leader Li asks us to fly, let's fly, I believe in Leader Li's judgment."

"What may be impossible, it has to be based on facts, unless you send sappers first and blow up a road...... Hey, what's next? ”

Wang Hu's eyes looked down and saw a camouflage-painted armored car appearing on a big rock, and he was immediately stunned: "It's really that big eight-wheeler, they, they have driven more than ten kilometers in the pile of rubble, this is simply impossible!" ”

Even if the tracked vehicle can't pass, how did this wheeled vehicle come over? Looking at the puffs of black smoke coming out of the exhaust pipe behind the car, and watching the tires turn on the huge stones, Wang Hu's eyes widened.

Zhang Cheng smiled: "Half of the way has been walked, and the rest of the road will definitely not be difficult for them, it seems that Leader Li guessed correctly." ”

"No, there is a big rift valley ahead, five meters wide, they can't get around, they can't drive through, and when they get there, they will definitely have to turn around and come back."

In addition to the stones, there are also rifts! This is the most fatal, Wang Hu feels that they can't get by, and it's also because of this.

Tracked vehicles can cross some trenches, but there are prerequisites, in general, the width of the trench cannot exceed half of the length of the track, and for safety, it is better not to exceed a third, so that even a part of it can be suspended in the air.

And the wheeled infantry fighting vehicle below, the length is only eight meters, it is still wheeled, the distance between the first row and the fourth row of wheels is less than seven meters, and it is sure to cross a two-meter-wide trench, this kind of five-meter-wide rift, don't even think about it!

Zhang Cheng looked down, yes, it was indeed difficult, but ...... Since they can drive all the way here, they must be sure!

"They're moving below, unlike us who can see clearly from above, and don't even know that there's a rift ahead, so we'll have to turn around later!" Wang Hu made a judgment.

At this time, on the armored car below, Xu Dashou was the first to see the plane overhead.

"Mr. Qin, there are two flying machines on your head, it's very strange."

Qin Feng glanced at it: "Well, the three jumpers, they must have been sent by Leader Li to pick us up, don't worry about them." ”

If there is a heavy Mi-26, they will be hoisted over directly, which will save trouble, but there is no domestic ah, the load of the three jumpers is a hundred catties, and they can only come to see a few times, and at most take one person away.

Let's see, let them see how we work miracles.

"Mr. Qin, we have arrived at the rift valley area in front!"

There is no way to avoid this, and after some research, this route is the most suitable, but it will be through this rift, but we have already planned it!

"Okay, stop at that big rock!"

Amid the roar of the engine, the big eight wheels climbed up a large rock, majestic, and from here you can overlook the Great Rift Valley.

"The Great Rift Valley has finally been discovered." Wang Hu looked at the scene below: "I dare to assert that next, they will have to turn around and go back and look for other paths." However, it seems that there is no other way, and they may have to drive back. Hey, what is he doing? Hurry up, fly farther! ”

The Big Eight Wheel has not yet been officially finalized, but there are still things that should be there, such as a small turret poked on it, and on the outside of the turret, there are special pylons for firing Red Arrow-73 anti-tank missiles.

This kind of wire-operated anti-tank missile is no different from a model airplane, it flies very slowly, and there are branches along the way and it is easy to hang on to the towed wires and cause it to crash, but it is still a model that is equipped with a large number of equipment in the army at present.

It's cheap after all.

This big eight wheels are also equipped, and this time they are still with it!

Before the car set off, he proposed to simulate the actual combat state as much as possible, so he loaded some more materials and some weapons.

How expensive is this thing? If this thing is typed out here, what will I do if I am asked afterwards? This is all in the future, and Qin Feng also has a good reason, in short, now, Qin Feng has to do this.

No road? Then blow up a way out!

A few minutes later, a ball of flame came out of the tail of the Red Arrow-73, and when it first took off, it swayed as if it could fall at any moment, flew for a while before stabilizing, and then, crashed into the opposite side of the Great Rift Valley.

Rumble!

As the explosion sounded, flames rose, stone chips flew, and some even smashed into the armored car, crackling.

This Mr. Qin is so bold, he can do anything! Moreover, the choice of impact point is very suitable!

Boom, boom......

If you want an anti-tank missile to blow up the entire stone wall, you have to pay attention to it, and this position of the explosion at this time is exactly the most vulnerable place on the stone wall, with the explosion, the bottom collapses, and the stones above roll down into the Great Rift Valley, so the Great Rift Valley is filled!

Not all of them were filled, however, the width of the Great Rift Valley has changed from just five meters to less than three meters wide!

"Awesome, Mr. Qin's style, I like it!" Wang Hu sighed.

"This three jumpers in the air were also invented by Mr. Qin." Zhang Cheng said: "It's simply a sharp weapon for our special operations, when you get to the target, you can turn off the engine and float over, I have long liked Mr. Qin and them, but this ditch is still a little wide, Mr. Qin and they ......"

"What are they going to do? Do you want to fly over? Wang Hu watched puffs of black smoke coming out of the exhaust pipe, and it was obvious that the driver was stepping on the accelerator, did he want to fly?

Sure enough, in the next second, the big eight wheels drove at full power, rushing forward, the speed of the car was extremely fast, although it only rushed a few dozen meters, the speed was already over sixty, no, it should be more than seventy kilometers per hour, and the place where it rushed out happened to be an inclined plane.

In the air, look at this scene even more spectacular! I saw the car draw a graceful arc and fly to the opposite side!

At this moment, Qin Feng was also in a state of flux, and his wheeled infantry fighting vehicle seemed to have been transformed into five pairs of load-bearing wheels.

59 Star Destroyer, take off!

"Mr. Qin is really a genius!" Wang Hu sighed again.

Although the wheeled infantry fighting vehicle had only flown to the highest point, he could see that this vehicle could fly over the entire Great Rift Valley, and there was no need to blow up the stone wall on the Great Rift Valley at all, and even if it collapsed, the place where the collapse was unstable, and falling down was likely to cause a collapse again, and finally it would be all over.

It blew up the opposite side, just to blow up a gap that could fly over from this side and fall smoothly! It's just a place to stay.

"Yes, Mr. Qin's brain is different from ordinary people!" Zhang Cheng also sighed.

Ahh

Qin Feng sneezed.

Boom!

The car fell heavily on the opposite side, at this moment, Xing Fuqiang didn't have time to worry about Qin Feng, what he had to worry about was the suspension of the big eight wheels, could he withstand this kind of impact?

Absolutely! In the previous tests, they often drove the big eight wheels up from the dirt road, and then fell, the hanging material, with 80,000 tons of die forging presses pressed, how could it not withstand this kind of impact?

Moreover, due to the smooth flight, the eight wheels landed almost simultaneously, the tires were cushioned, the suspension cushioned, the seats cushioned, and none of the three people inside felt too much bump.

Boom, boom!

It's a pity that the computer monitor was not tied properly and actually fell from a box in the back!

I don't know if it's broken, Qin Feng is a little distressed, if this thing is broken, Li Runzhu has to pay for it!

Xing Fuqiang kicked the accelerator, and the big eight wheels continued to jump forward.

In the sky, on the two air jumpers responsible for responding, Zhang Cheng and Wang Hu were dumbfounded.

"It seems that they don't have any problems passing through here, Wang Hu, you continue to supervise here, and I'll go back and report!"

The three jumpers in the air are small and lightweight, and they only carry a close-range radio equipment, and if they want to contact the rear shooting range, they have to fly back.

"Good!"

Time passed quickly, and in the blink of an eye it was noon.

Ma Bonian, the person in charge of the national shooting range, looked at the crowd of people who came with a smile, and then looked at Li Runzhu, who led the team.

"Lao Li, the time is just right, let's go eat."

"Don't worry, don't worry, I'll wait for Qin Feng and them to come and eat together."

Ma Bonian was stunned: "Lao Li, are you so sure that they will come closer?" Even if you really take this road, it is estimated that you will have to toss a few times back and forth on the side of the rocky hill, and you won't be able to get out until dark. ”

Li Runzhu smiled: "Old Ma, why don't we make a bet?" ”

Before Ma Bonian nodded, there was a buzzing sound outside, and a Falcon gyroplane landed, and just after it stopped, Zhang Chengcheng ran over from above.

"Report to the leaders, the big eight wheels of the Pacific Group have really taken the nearest route!"

"Where have they been?"

"They had already flown over the Great Rift Valley before I flew back, and they should have passed the rocky hill by now."

"Wait, what did you say, they flew over the Great Rift Valley?"

"Yes, it's the ...... that flew by"

The big guys didn't eat, and they were dumbfounded when they heard Zhang Cheng talk about what he had just seen.

"So, it's better than a hammer!" Ma Bonian said: "With this car being able to cross the rocky hill and fly over the Great Rift Valley, this car is the most suitable choice for the army!" If the others are not convinced, then try it again, grandma's, cow! ”
