Chapter 4 Magnetic Field Disorders

His father was a physics professor at a university in Xiangyang, and Linto's multi-function watch was a birthday present, but unfortunately it seemed to be a regrettable half-finished product.

"I'm sorry, baby, the recording function was not ported very successfully, I immediately improved it."

"Why didn't you say it when you gave it to me? Hmph, it was tricked to test it anyway. ”

Seeing that his son was unhappy, Dad Lin threw him a digital camera and said, "Does baby like photography?" The camera is easy to operate and supports both night mode and panorama mode, making it perfect for beginners. ”

"How many pixels?" Linto asked, looking up.

"Pixels really aren't the only criterion by which digital cameras are judged."

"Well, that's not all I care about."

"One thousand sixteen."

"You're embarrassed to take out the pixels like this? Isn't it fun for me to use my phone? Linto said flattened.

Dad Lin regained his majesty as a father and said: "Compared with those mainstream cameras on the market, it has improved noise reduction and speed, although it is mainly used for still life shooting, it can also support thermal imaging shooting." ”

"What is a thermal imaging shot?"

"First of all, we have to talk about it separately, and when we talk about thermography, we have to talk about thermal imaging cameras. Any object that uses temperature emits infrared rays, and a thermal imaging camera receives infrared rays emitted by the object and displays the temperature distribution of the surface of the object to be measured through a colored picture. In layman's terms, a thermal imaging camera converts the invisible infrared energy emitted by an object into a visible thermal image. ”

"Oh, I see, thermal imaging is really taking this thermal image."

"Yes, smart."

"Sounds like it's worth playing, thank you, Dad."

Leaving the studio, Lintor went home and fiddled with the newly acquired digital camera.

He made real-time observations of his small room, replaced the ordinary real scene with a thermal image, and sensed the temperature changes of different objects, which were mainly divided into blue, green, yellow, and red domains, with strong color contrast. But its shortcomings are also obvious, when there is a moving object in the picture, the image will become very blurry, and then affect other areas, and the effect of the shot will be completely ruined.

Playing like this, he actually forgot the time, an afternoon passed quickly, and the content assigned by the teacher today could not be completed, so it could only be put into tomorrow.

After dinner, Lin Tuo put the camera aside and concentrated on writing the homework of each subject, at this time Sister Su Muyu should be back, ask her if you don't understand any questions.

On Sunday morning, in order to be able to write this headache-inducing review, Linto decided to go to the farm again.

On this day, he brought the thermal imaging digital camera given by his father, and told the farm manager before entering the field that he was not here to visit today, but to inspect. Yesterday I had seen all the places, but the fishing ground had not yet been entered, so Linto wanted to take a look.

On the edge of the lake at the fishing ground stood a wooden sign that read, "Do not approach idlers", which was beautifully ignored by Linto. He had learned the art of fishing from anglers before, but he had never put it into practice, so now he couldn't catch even a small fish.

Linto took out his camera to observe the surface of the lake, the gentle sunlight shining down, the surface of the water was sparkling, it was the kind of cold dark blue, and the water was even blacker, indicating that the heat did not remain. Then, he pulled back to observe the distant scene, and the infrared light did not sense, so he slowly zoomed in the picture.

When the fishing platform in the center of the lake appeared in the picture, it should have been transformed into a thermal image, but for some reason, the picture suddenly blossomed, turned into a broken mosaic and froze, and Linto also had a nasty sense of dazzle.

He closed his eyes and rubbed them, the discomfort gradually disappeared, and the camera picture became normal. In order to find out why, Linto shot at the Diaoyutai again, and this time the image was clear and clear, and there was no problem.

He thought it was a minor problem with the camera, because his dad gave him these test items as gifts. But the products researched by my father are very humane, even if they are clumsy, they will not have a harmful effect on people.

Linto shook his head and looked around, could it be the influence of external factors?

"Hey, you just took a picture, didn't you?"

There was a sudden voice behind him, and he quickly turned around in surprise, only to see a boy standing there, wearing a blue jacket and sweatpants.

"Damn, it's you again?" He was the same junior high school boy from yesterday, and it scared him every time.

"Yes, it's me." The boy's voice drifted into his ears like a soft wind, "I didn't have time to introduce myself yesterday, my name is Figley, and I am in the first class of junior high school." ”

"I'm Linto, fifth grade 3rd class."

"I know, it's on your student card."

Linto bowed his head a little shyly, he did have a school card around his neck yesterday. He looked at Figley with a resentful look, this man always came to do bad things to him.

"What kind of camera are you?" Figley pointed to what he was holding.

"Hahaha, why should I tell you?"

"It's the first time I've seen a digital camera equipped with a thermal imaging camera."

"Ahahahaha, then I'll tell you, my dad is a professor at Xiangyang University, and he made this camera." Linto wiped his nose triumphantly.

"Unfortunately, there was a glitch?"

It turned out that he had seen it just now, and now Linto couldn't hide it. On the other hand, he has always admired those who are more knowledgeable than him, whether they are two-dimensional fanatics or wanderers who pick up rags.

"That's none of your business."

"Looks like we're the same kind." Figley took out the portable device in his backpack and said, "Introduce my partner, this is a small air detector that mainly detects some polluting gases and harmful dusts in the air, such as formaldehyde and benzene. ”

When Linto heard this, he immediately showed great interest, and asked with a big grin: "Oh, what are the magnetic needles and blades on the back?" ”

"The magnetic needle is used to measure the direction of the magnetic field, and the blade is part of the wind vane, which, as the name suggests, determines the direction and strength of the wind."

"Oh oh oh my God, isn't that awesome!" Lintor stared at the instrument and cheered, Figley could see the glint in his large eyes.

"What was the result?"

"There was no problem, the air on this farm was clean, but just now, the direction of the magnetic needle changed drastically. It's only been for a moment, but it's already told me that the magnetic field is out of order. ”

"What if it's disordered?"

"It's too early for you to know this, I'll tell you when you get to junior high school." Then, in a lower voice, he said, "Interestingly, though, the magnetic field anomaly coincides with the time when your camera malfunctions. ”

"Oh? Is it because of the abnormal magnetic field that causes the failure? ”

"Theoretically, there is no fundamental connection between the two."

In this case, there is really no problem with his own camera, it can only be the external environment that affects it. If it is placed in normal times, Linto will not delve into difficult problems, as long as he deals with the common sense around him. His father also said that early exposure to this too difficult knowledge will cause the brain to suddenly short-circuit.

In addition to "Nature and Science", Lintor also watches other science and technology programs or books, aiming to understand them within his own knowledge.

Neither of them could understand the principle behind this, so Linto exchanged chat software accounts with him, hoping to take him to his father one day.
