Open an aircraft carrier to fight against Japan

Lin Yuan watched her gradually disappearing back, feeling helpless in his heart. When he came to the newspaper office, he saw that it was busy inside. Everyone was lying on the table, writing and drawing. Lin Yuan walked inside and came to the newspaper office. Shen Wanqing was in the editor's office. As soon as she arrived at the door, she heard a burst of men and women talking and laughing inside.

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

When the man saw Lin Yuan coming, he got up and said goodbye. As soon as the man left, Lin Yuan asked, "Who is he? Why does he look familiar to me?"

Shen Wanqing smiled and said: "So you met him before, he is a British spy, he wanted to seduce me to obtain information, but he was not good enough, he didn't get our information, but I got their information. few."

Lin Yuan quickly asked: "If you have any information, tell me quickly."

Shen Wanqing thought for a while and said: "It's all about the navy, but it's too scattered. I'll tell you after I sort it out. I can give you a spoiler in advance. This news is absolutely shocking! 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 on it, and said maliciously: "Who is this person?"

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

Shen Wanqing opened the safe, took out the laptop from inside, and said disdainfully: "There are so many people on board, how could I know everyone?"

Shen Wanqing said, uploading the photo to the computer, and then said: "How do I change it?"

Lin Yuan smiled and said, "Help me change the background to one that looks like a fairyland, and then add a few words on it."

Shen Wanqing fiddled with the computer for a while, and said, "It's done." Lin Yuan poked his head to take a look, and saw that the background behind Chen Xin had been replaced by a valley, which was full of flowers. Lin Yuan nodded and smiled. Said: "Okay, that's all right, can you print out the photos for me?"

Shen Wanqing nodded, and took out a small printer from the safe. After a while, the photo was printed out. Lin Yuan took the photo and said, "I want to convert it into a holographic form. Warehouse?"

Shen Wanqing said: "The holographic projector is indeed in the warehouse, but I don't know how to use it."

Lin Yuan smiled and said, "It's okay, I know how to use it, you take me there, and I will use it."

The two came out of the newspaper office, and were allowed to enter the warehouse after going through strict identity checks outside the warehouse. After all, there were a lot of things beyond the times in the warehouse.

The warehouse was very dark and there were no lights for lighting, so the two of them walked inside with flashlights, and soon Shen Wanqing stopped in front of a shelf, pointed to the box in front of him, and said, "Then It's a holographic projector."

Lin Yuan nodded and asked, "It's not enough to have a projector. I also need a hologram. Where is it?"

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

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 laser is not powerful, it is better to wear goggles. .”

After Lin Yuan finished speaking, he started to adjust the camera, fixed Chen Xin's photo on the shelf, then took out the reflector and photosensitive film from the camera, and put them on the platform. Shen Wanqing watched Lin Yuan adjust the mirror and photosensitive film. The position of the film, asked: "I also often hear about laser holography, what does 'holography' mean?"

Lin Yuan smiled and said: "'Holography' can be understood as 'all information'. Light is a kind of electromagnetic wave. Electromagnetic waves have three kinds of information: amplitude, frequency and phase. Our ordinary photography and movies are only applied to light. Amplitude and frequency information, but phase information is not used at all, and holographic technology uses phase information, so it is called 'holography', such technology can provide us with three-dimensional images."

Shen Wanqing asked: "Then how can we record the phase of light?"

Lin Yuan didn't answer, but asked suddenly: "Have you been to high school?"

Shen Wanqing couldn't help laughing, and said, "Of course I passed the exam, I'm still a good student with both good character and academics."

Lin Yuan said: "Then you must have studied physics, right? You must have heard of the double-slit interference experiment. In this experiment, a beam of light hits two narrow slits, and interference occurs when passing through the narrow slits. Alternate light and dark interference fringes are formed on the imaging plate, if we replace one narrow slit with an object, and the other narrow slit with a reference light source," Lin Yuan pointed at the camera 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. At this time, we can replace the imaging plate with a photosensitive film to record the interference fringes. When we look at it, we can use the projector to release it, and we can get It turns out that the object has been resembling."

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

It turned out that Lin Yuan ignored one thing, that is, holography can include all the information of the image, so the image formed after shooting looks like a photo. Looking at such a picture, no one will definitely put it on the picture. people as fairies.

Lin Yuan frowned tightly, and said to himself: "What should I do? It seems that this method will not work. If you want to take a real picture, you must have a three-dimensional image. Is there any way to do it? How about turning a photo into a picture?"

Shen Wanqing smiled and said, "Isn't it just a three-dimensional image, I have a solution."

Lin Yuan asked, "What can you do?"

Shen Wanqing smiled and said, "Don't you remember an advanced technology? It's called laser rapid prototyping."

Any object is composed of a series of planes. These planes are laid together in the height direction to form a three-dimensional object. Laser rapid prototyping is to use a series of powder materials to lay out the object layer by layer. After laying out, With laser sintering and solidification, a three-dimensional object is formed. This technology is often used in the manufacture of molds.

Lin Yuan said: "That's right, why did I forget about laser rapid prototyping? We can make a body for Sister Chen's image according to the female body parameters, then make a background, and then use holography to take a photo. Is that enough?"

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 three-dimensional model, and then send the data to the arsenal. The arsenal will be able to produce the model within today. , when we shoot it again, you can use it to deceive people in the Qing court."
