In Mo Yanran's laboratory at the Huxiaoling base, Aiya looked at Mo Yanran with a longing look on her face, her eyes sparkling with a desire for knowledge. Around her, other technicians in the laboratory also gathered around, using the same
He stared at Mo Yanran with his eyes.
Mo Yanran reached out and pushed the gold-rimmed eyes on the bridge of her nose, and then said slowly, "The so-called holographic technology refers to the technology of recording and reproducing the true three-dimensional image of an object using the principles of interference and diffraction."
People stared at him silently, and no one interrupted.
"I have already told you about interference, diffraction and three-dimensional imaging last time. Holographic technology is a science and technology based on these principles. It is a very advanced subject." Mo Yanran's voice was clear and very pleasant to the ears.
During this time, she taught these people some knowledge during the lunch break every day. Although they were relatively simple, these people sounded very interested and serious.
"The first step of holographic technology is to use the principle of interference to record the light wave information of the object. This is the shooting process: the object is irradiated by laser to form a diffuse object beam; the other part of the laser is used as a reference beam to shoot on the holographic film, and the object
The superposition of light beams produces interference, which changes the object's light waves on each side.
The phase and amplitude of the points are converted into spatially varying intensity, thereby using the contrast and spacing between the interference fringes to record all the information of the object's light waves. After the film recording the interference fringes undergoes development, fixing and other processing procedures, it becomes a
A hologram, or hologram.
The second step is to use the principle of diffraction to reproduce the object's light wave information. This is the imaging process: the hologram is like a complex grating. Under coherent laser irradiation, the diffracted light wave of a linearly recorded sinusoidal hologram can generally give two
Individual images, namely the original image (also called the initial image) and the conjugate image. The reproduced image stereo
It has strong sense and real visual effect. Each part of the hologram records the light information of each point on the object. Therefore, in principle, each part of it can reproduce the entire image of the original object. Through multiple exposures, the same image can be reproduced.
Multiple different images are recorded on the negative and can be displayed separately without interfering with each other."
In order to make them understand, Mo Yanran had already explained all the relevant knowledge to them in advance, so it was not too difficult for everyone. Among them, Aiya, Tan Tianyou and others sounded more relaxed.
Seeing that everyone was still listening, Mo Yanran continued, "The holographic principle is that a system can in principle be completely described by some degrees of freedom on its boundaries. It is a new theory based on the quantum properties of black holes..."
Her narration lasted for an hour, until the electromagnetic communicator on her wrist rang, and then she stopped without saying anything.
“Because the reconstructed three-dimensional image is conducive to preserving precious artwork materials for collection, every point is recorded on any point of the hologram during shooting. It doesn’t matter if the photo is damaged. The scenery in the holographic photo has a strong three-dimensional sense and vivid image.
It is lifelike and can be displayed at various exhibitions with the help of lasers. Therefore, holographic technology is widely used in various forms of waves, such as x-rays, microwaves, sound waves, electronic waves, etc. As long as these waves are formed
It is enough to have enough coherence when interfering with the pattern."
The electromagnetic communicator emitted a low beep and vibrated gently, reminding Mo Yanran who was a little fascinated and didn't want to stop.
Turning her head to look at the electromagnetic communicator on her wrist, Mo Yanran saw that the message was from Yan Beifeng, so she hurriedly ended today's lecture and walked into the room, "Optical holography can be applied to three-dimensional movies.
television, exhibition, microscopy, interference
Metrology, projection lithography, military reconnaissance and surveillance, underwater detection, internal metal detection, preservation of precious historical relics, artworks, information storage, remote sensing, etc. Okay, let’s stop here today and continue tomorrow.
I’ll give you the following content.”
Everyone was still unfinished, but knowing Mo Yanran's temper, they had no choice but to return to their seats with regret and continue their work.
Aiya swung her long hair into a ponytail and happily skipped back to her work station and started to get busy. She was in a very good mood because the knowledge taught by Mo Yanran today made her feel like she had seen another world.
The thirst for knowledge in my heart was aroused.
"Come early tomorrow, then you can continue to listen to Sister Yanran explain those things." Aiya smiled sweetly, but the work in her hands was not left behind, and she was still working in an orderly manner.
Mo Yanran walked into her office, closed the door, and turned on the communicator. Yan Beifeng's rich voice immediately came from inside, "Mo Yanran, Luo Xiao is back."
"What, Luo Xiao is back?!" Mo Yanran's voice suddenly rose an octave, causing Yan Beifeng's ears across from him to buzz. He quickly moved the communicator on his wrist farther away and continued,
"This time the Japanese attacked Hidden Dragon Mountain, but they helped us. Now that Hidden Dragon Mountain has been merged and became the Hidden Dragon Team, the strength of the Yanhuang Legion has been strengthened." You can hear Yan Beifeng's mood.
Very good, there is joy in the voice.
Mo Yanran didn't care about any of this. What she cared about was that Luo Xiao was back, so she told Yan Beifeng to come over immediately, and then turned off the communicator.
After turning off the communicator, Mo Yanran leaned against the chair and took a few deep breaths to calm down her excitement. She didn't know why she was so nervous when she was going to see Luo Xiao.
Reaching out to pull her messy hair, and looking at the colorful work clothes on her body, Mo Yanran not only frowned, "How can I go to see Luo Xiao like this?"
With this thought in his mind, he took off his work clothes as quickly as possible, and then opened the door leading to his residence...
In the laboratory, Tan Tianyou held an experimental report in his hand and was communicating with Aiya in a low voice. Suddenly, the door of Mo Yanran's office opened. They looked up and were stunned.
The experimental report in Tan Tianyou's hand unconsciously dropped down and glanced at Aiya's arm, but she didn't feel it at all and stared at the office door in a daze.
At the same time, everyone else also discovered this and stopped what they were doing one by one, looking at Mo Yanran at the office door with a strange expression.
At this time, Mo Yanran seemed to be a completely different person than usual. Her long hair was black and shiny, as if she had just washed it. It often reached her waist and hung down behind her back, and was casually tied behind her head with a blue rubber band.
, she was wearing a white sportswear, which made her tall and skinny
Her fair skin, cheeks flushed from bathing, and her slender neck made Tan Tianyou and the other men a little stunned. They swallowed unconsciously. Mo Yanran casually glanced at the people who were in a daze, strangely
Asked, "If you don't work, why are you watching me do it?"
"Oh, it's okay, it's okay, we'll get to work right away." People woke up and looked at her again reluctantly, then lowered their heads and continued working.
"These people are really weird today." Mo Yanran thought to herself, then opened the door and left the laboratory.
After Mo Yanran walked out, there was some movement in the laboratory. While everyone was working, they whispered about Mo Yanran's changes. No one knew why she, who used to dress so casually, seemed to have changed.
Start dressing up.
Of course, Mo Yanran still looks pretty when she dresses up. These men wish she could be happy dressing up like this every day.
