"Sister Yanran, what is holographic technology?"

In the Huxiaoling Base, in Mo Yanran's laboratory, Aya looked at Mo Yanran eagerly, her eyes sparkling with desire for knowledge.Beside her, other technicians in the laboratory also gathered together, staring at Mo Yanran with the same eyes.

Mo Yanran stretched out her hand and pushed the gold-rimmed eyes on the bridge of her nose, and said unhurriedly, "The so-called holographic technology refers to the recording and reproduction technology of using the principles of interference and diffraction to record and reproduce the real three-dimensional images of objects."

Everyone watched 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 pleasant, During this period of time, during the break at noon every day, she gave some knowledge to these people. Although it was relatively simple in later generations, these people seemed to be interested and very serious.

"The first step of holographic technology is to use the interference principle to record the light wave information of the object, which is the shooting process: the object to be photographed forms a diffuse object beam under laser irradiation; The superposition of light beams produces interference, which converts the phase and amplitude of each point on the object light wave into a spatially varying intensity, so that all information of the object light wave is recorded by using the contrast and interval between the interference fringes. The film recording the interference fringes is developed , fixing and other processing procedures, it becomes a hologram, or hologram.

The second step is to use the principle of diffraction to reproduce the light wave information of the object. This is the imaging process: the hologram is like a complex grating. There are two images, that is, the original image (also known as the initial image) and the conjugate image.The reproduced image has a strong three-dimensional effect and has a real visual effect.Each part of the hologram records the optical information of each point on the object, so in principle, each part of it can reproduce the entire image of the original object, and multiple different images can be recorded on the same film through multiple exposures. And they can be displayed separately without interfering with each other. "

In order for them to understand, Mo Yanran had already told them all the relevant knowledge in advance, so everyone didn't sound too strenuous, and among them, Aiya and Tan Tianyou sounded more relaxed.

Seeing that everyone was still listening, Mo Yanran continued, "The holographic principle is that a system can be completely described by some degrees of freedom on its boundary in principle, and it is a new theory proposed 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.

"Because the reconstructed three-dimensional image is conducive to the preservation of precious art materials for collection, every point is recorded on any point of the hologram when shooting, and it does not matter if the photo is damaged. The scene of the hologram has a strong sense of three-dimensionality. Realistic, with the help of lasers, it can be displayed in various exhibitions and other characteristics and advantages, so 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 Just enough coherence when interfering patterns."

The electromagnetic communicator made a low beep and vibrated slightly, 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 then walked into the room, "Optical holography can be applied to stereoscopic movies, Television, exhibitions, microscopy, interferometry, projection lithography, military reconnaissance and surveillance, underwater detection, metal interior detection, preservation of precious historical relics, artwork, information storage, remote sensing, etc. Well, today Let’s talk about this first, and I will give you the following content tomorrow.”

Everyone still had a lot to say, but knowing Mo Yanran's temper, they could only return to their seats with regret, and continued their work.

Aya shook her long hair tied into a ponytail, happily jumped back to her job, and started to get busy. She was in a very good mood, because the knowledge Mo Yanran taught today made her seem to see another world. The thirst for knowledge in my heart was aroused.

"Come early tomorrow, then you can continue to listen to Sister Yanran's delivery of those things." Aiya smiled, 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 with her hands back, and then turned on the communicator, and immediately Yan Beifeng's deep voice came from inside, "Mo Yanran, Luo Xiao is back."

"What, Luo Xiao is back?!" Mo Yanran's voice suddenly increased by an octave, causing the ears of Yan Beifeng on the opposite side to buzz. She quickly moved the communicator on her wrist to the distance, and continued, "The Japanese attacked Hidden Dragon Mountain this time, but it helped us. Now that Hidden Dragon Mountain has been merged into the Hidden Dragon Team, the strength of the Yanhuang Legion has been strengthened." It can be heard that Yan Beifeng is also in a bad mood. Very good, with joy in the voice.

Mo Yanran didn't care about these things, 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?

Stretching out her hand to tug at her disheveled hair, and looking at the colorful work clothes on her body, Mo Yanran not only frowned, "No way, how can I go to see Luo Xiao like this."

With that in 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 was holding an experiment report in his hand, and was communicating with Aiya in a low voice, when suddenly the door of Mo Yanran's office opened, they looked up and were stunned.

The experimental report in Tan Tianyou's hand hung down unconsciously, sweeping Aya's arm, but she didn't feel it at all, and also stared at the office door in a daze.

At the same time, other people also found out about this, and stopped their work 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, and it was often waist-length hanging behind her head, tied casually behind her head with a blue rubber band. , she was wearing a set of white sportswear, which made her tall and fair-skinned, her flushed cheeks from the bath and her slender neck made Tan Tianyou's men a little stunned, and they all unconsciously Mo Yanran swallowed her saliva, casually glanced at the people who were in a daze, and asked strangely, "Why are you watching me when you don't work?"

"Oh, it's all right, we'll get to work right away." Then people came to their senses, looked at her reluctantly, and then bowed their heads and continued to work.

"These people are really strange today." Mo Yanran thought in her heart, and then opened the door and left the laboratory.

After Mo Yanran walked out, there was some movement in the laboratory. While working, everyone was discussing Mo Yanran's changes in low voices.No one knew why she, who used to dress so casually, turned into a different person and began to dress up.

Of course, Mo Yanran still looks good when she dresses up. These men wish she could be happy every day when she dresses up like this.
