Lin Yuan looked at her back gradually moving away, and felt helpless for a while, when he came to the newspaper office, he saw that it was busy, everyone was lying on the table, writing and drawing, Lin Yuan walked inside, and came to the editor-in-chief's room where Shen Wanqing was, and as soon as he arrived at the door, he heard a burst of laughter from men and women inside.

Lin Yuan heard the voice of a strange man in the room, and couldn't help but feel a little uncomfortable in his heart, but he couldn't say what it was like, he knocked on the door, Shen Wanqing said please come in inside, Lin Yuan pushed the door in, and saw a blond man talking to Shen Wanqing.

When the man saw Lin Yuan coming, he got up to say goodbye, and as soon as the man left, Lin Yuan asked, "Who is he?" How do I look familiar? ”

Shen Wanqing said with a smile: "You have seen him before, he is a British spy, and he wants to seduce me to obtain information, but he can't work hard at home, and he didn't get our information, but I got a lot of their information." ”

Lin Yuan hurriedly asked, "What information do you have, hurry up and tell me." ”

Shen Wanqing thought for a while and said: "It's all about the navy, but it's too scattered, wait for me to sort it out and tell you, I can give you a spoiler in advance, this news is absolutely shocking!" Do you have something to do with me? ”

Lin Yuan took out the communicator, adjusted Chen Xin's photo, and said, "Help me process this photo." ”

Shen Wanqing took the communicator, looked at the person above, and said ill-intentionedly, "Who is this person?" ”

Lin Yuan smiled: "Her name is Chen Xin, and she is the doctor on our ship, what's wrong?" Don't you know her? ”

Shen Wanqing opened the safe and took out the laptop from it, and said disdainfully: "There are so many people on the ship, how can I know all of them?" ”

Shen Wanqing said and uploaded the photo to the computer, and then said, "How do you want me to change it?" ”

Lin Yuan smiled: "Help me replace the background and replace it with a fairyland-like one, and then add a few words on it." ”

Shen Wanqing fiddled on the computer for a while and said, "It's done." Lin Yuan poked his head to take a look, only to see that the background behind Chen Xin had been replaced with a valley, and the valley was full of flowers, Lin Yuan nodded and smiled: "Okay, that's it, can you help me print out the photo?" ”

Shen Wanqing nodded, and took out a small printer from the safe, and after a while, the photo was printed, Lin Yuan took the photo and said, "I'm going to convert it into a holographic form, the holographic projector is in the warehouse, right?" ”

Shen Wanqing said: "The holographic projector is indeed in the warehouse, but I won't use it." ”

Lin Yuan smiled: "It's okay, I'll use it, you take me there, I'll use it." ”

The two of them came out of the newspaper office and were allowed to enter the warehouse after a strict identity check outside the warehouse, after all, there were a lot of things that were ahead of their time.

The warehouse was very dark, and there was no lighting for lighting, so the two of them turned on their flashlights and walked inside, and soon Shen Wanqing stopped in front of a shelf, pointed to the box in front of her with her hand, and said, "That's the holographic projector." ”

Lin Yuan nodded and asked, "It's not enough to have a projector, I still need a holographic camera, where is it?" ”

Shen Wanqing walked around the warehouse for a while, then took out a small box and said, "This is the filmmaker." ”

Lin Yuan put the camera on the platform, then took down two laser goggles from the shelf, and said: "The main body of the camera is a laser source, although the intensity of this laser is not large, it is better to wear goggles." ”

After Lin Yuan finished speaking, he began to debug the camera, fixed Chen Xin's photo on the shelf, and then took out the reflector and photosensitive film from the camera and put it on the platform, Shen Wanqing watched Lin Yuan adjust the position of the transmitter and photosensitive film, and asked: "I often hear about laser holographic technology, what does 'holographic' mean?" ”

Lin Yuan said with a smile: "'Holographic' can be understood as the meaning of 'all information', light is a kind of electromagnetic wave, electromagnetic wave has amplitude, frequency and phase of these three kinds of information, our ordinary photography, movies, are only applied to the amplitude and frequency information of light, and the phase information is not used at all, and holographic photography technology, the phase information is also used, so it is called 'holographic', such a technique, can provide us with three-dimensional images." ”

Shen Wanqing asked, "Then what method can be used to record the phase of light?" ”

Lin Yuan didn't answer, but suddenly asked, "You went to high school, right?" ”

Shen Wanqing couldn't help but smile and said, "Of course I did, I'm still a good student with excellent character and learning." ”

Lin Yuan said: "Then you must have studied physics, right?" Double-slit interference experiment, you must have heard of it, in this experiment, a beam of light shoots at two narrow slits, and when it passes through the narrow slit, interference occurs when it passes through the narrow slit, forming light and dark interference fringes on the imaging plate, if we replace one narrow slit with an object, and the other narrow slit is replaced with a reference light source," said Lin Yuan with a finger to the camera with his hand, and said with a smile: "This is the reference light source - laser." ”

"Then the light of the object will interfere with the light of the reference light source, and then we can replace the imaging plate with photosensitive film, and then we can record the interference fringes, and when we look at it, we can use the projector to release it, and we can get the image of the original object."

Lin Yuan said, turned on the laser, and a beam of red light shone on the photo, and after a while, Lin Yuan turned off the laser, then took out the photosensitive film, and said, "Okay, we're done shooting." Lin Yuan said and put the photosensitive film into the projector, and when the image was released, Shen Wanqing laughed and said, "Are you going to use this to confuse those people in the Qing court?" ”

It turned out that Lin Yuan ignored one thing, that is, holographic photography can contain all the information of the image, so the image formed after shooting still looks like a photo, looking at such a picture, no one will definitely regard the person in the picture as a fairy.

Lin Yuan tightened his eyebrows and said to himself, "What should I do?" It seems that this method will not work, if you want to shoot realistically, it is definitely not enough to have a photo, you must have a three-dimensional image, is there any way to turn a photo into a picture? ”

Shen Wanqing smiled: "It's not a three-dimensional image, I have a way." ”

Lin Yuan asked, "What can you do?" ”

Shen Wanqing smiled: "Don't you remember an advanced technique?" It's called laser rapid prototyping. ”

Any object is composed of a series of planes, these planes are laid together in the height direction, it constitutes a three-dimensional object, laser rapid prototyping is to use a series of powder materials to lay out the object layer by layer, after paving, with laser sintering and solidification, it forms a three-dimensional object, this technique is often used in the manufacture of molds.

Lin Yuan said: "Yes, how did I forget about laser rapid prototyping? We can make a body for Sister Chen's image according to the female body parameters, and then make a background, and then use holography to take a photo, isn't it? ”

Shen Wanqing replied: "That's right, our arsenal has several sets of rapid prototyping machines, I will go back and set the parameters of the dioramature, and then transmit the data to the arsenal, the arsenal can get the model out today, and then we will shoot it, and you can use it to deceive the people of the Qing court." ”
