"The metrology of old time and space is divided into ten categories. I think the mechanical industry relies on two categories: 'geometric quantity metrology' and 'mechanical metrology'. Among them, the measurement of geometric quantities relies heavily on your optical equipment. For example, the Michelson interferometer, after all
The optical measurement method is highly accurate!”
Only then did Lin Hanlong understand why Yuan Haowen was so enthusiastic about him. Then he continued the topic: "It's not difficult to make a Michelson interferometer, but I don't know anything about the 'measurement' you are talking about. I'm afraid it won't be useful for you when I make it."
When Yuan Haowen saw that Lin Hanlong had taken the bait, he was overjoyed: "It doesn't matter. I'm responsible for the mechanical processing. I also have interferometer data for measurement from the old time and space. This is a completely new field."
The two men had a long discussion about measurement issues, especially about some issues regarding measuring tools and precision tools. It can be said that the two sides met each other late. The conversation lasted until late at night.
It was already midnight when Lin Hanlong returned home from Yuan Haowen. Cai Junjie sent his master to the door of the apartment and complained in a low voice: "Master, I just came back from a business trip for several days, and I didn't come home until so late!"
"You little monkey, it's none of your business!" Lin Hanlong was in a good mood and rewarded his apprentice with a chestnut, "You're not my wife!"
"Well, although I'm not your wife, the ladies have some opinions..."
"If you have an opinion, just give it an opinion. If you have an opinion, you can't live well?" Lin Hanlong waved his hand, "Stop talking about it and go back quickly."
"What time will I pick you up tomorrow?"
"Seven o'clock in the morning."
"It is too early……"
"roll!"
Cai Junjie wanted to persuade him again, but when he thought about his master's temper, he simply stopped talking and left with the coachman.
When Lin Hanlong returned home, the light in the foyer was still on, and the room was already silent. Lin Guanyu used to always wait for him in the foyer, but he didn't come home every day, and sometimes he would let her wait on the chair all night.
Lin Hanlong felt sorry and stipulated that there would be no need to wait for him to come home after ten o'clock in the evening, and the family could do what they wanted.
He looked towards the inner corridor. The door to the room was closed and it was pitch dark. Everyone was asleep. Recently, his daughter slept much more peacefully at night and stopped making noises at night. Lin Hanlong wanted to see his daughter. When he thought of her and Sonia
They were probably all fast asleep. If I went in, I would be disturbed again, so I decided not to go.
After washing up, he took a rest in his studio - because he came home at irregular times, and no one would like to have someone climb into bed suddenly while he was sleeping soundly in the middle of the night. So when the house got bigger, he built a studio for himself.
There is a small bed inside. If you come back late, you can rest here.
He slept until daylight. Lin Hanlong looked at his watch and it was already half past six. He quickly got up and took a shower. Lin Guanyu had already made breakfast and was waiting for him to eat.
"Still asleep?" Lin Hanlong asked.
"Well, I'm still asleep." Lin Guanyu whispered, "There was another commotion at dawn."
"That's right," Lin Hanlong said, "I didn't hear anything."
"Of course you didn't hear anything." Lin Guanyu said with a slight complaint, "You were snoring so much that you could hear it outside the door." Then she started to serve him porridge.
"Is it that loud?" Lin Hanlong didn't believe it, "Then I have to go to the hospital to have a look."
"If you snore, you should see a doctor. The doctor will not laugh at you."
"You don't understand." Lin Hanlong was slightly regretful. If it were Sonia, she would definitely explore why snoring requires seeing a doctor, and then initiate a discussion about breathing and human body structure.
Lin Guanyu is actually very similar to some of his elder relatives. She has a gentle temperament and cares about her family meticulously, but she has no education. She always relies on the experience accumulated over the years and the teachings of people in her previous life. Although she feels very warm and appropriate, she does not have any knowledge.
We can continue to have in-depth exchanges.
"I don't understand, I don't understand. You go find someone who understands!" Lin Guanyu became a little angry. He placed a basket of steamed dumplings heavily on the table and turned around to go back to the kitchen.
Lin Hanlong grabbed Lin Guanyu's waist and said with a smile (100,000 words deleted below)... Then he calmly stood up, straightened his clothes, and ordered: "Don't leave me food tonight, I guess I have some work to do."
."
Lin Guanyu nodded silently, touched her hair again, and asked, "Is my hair not messy?"
Lin Hanlong touched her head and said with a smile: "Not a trace of chaos."
After saying that, he picked up his bag and went out. He saw Cai Junjie and the driver already waiting outside. When Cai Junjie saw Lin Hanlong coming out, he hurriedly greeted him and said, "Master, it's almost half past seven..."
"Didn't you say yesterday that it would be too early to pick you up at seven o'clock?"
Cai Junjie was at a loss for words, thinking that it was all your fault! But he did not dare to refute and could only complain: "But the pass I applied for for the coachman is only valid until 7:30..."
"Then let's hurry up." Lin Hanlong was in a good mood. He got on the Venus Zero and stepped on the footbell, "Let's go!"
Lin Hanlong went to the optical factory and inspected the workshop as usual, checking the production records of the night shift. He also randomly inspected a few products produced by the night shift last night. The rate of authenticity is increasing every month. Our industrial upgrading is still effective.
.he thinks.
"Has the prototype of the projection imager been produced?" he asked Cai Shengjie.
"Five units have been made, and several more are being assembled and tested."
"Tell them to hurry up, the museum is waiting for use." Lin Hanlong thought helplessly that since Sonia went to work in the museum, the remote exploration team often came to "open the back door" when applying for equipment, "If it is done, you can test it yourself."
"Yes." Cai Shengjie knew that he valued the "user experience" of these devices.
A projection plotter is an optical instrument used to assist artists when painting. A lens is used to perform an optical overprint of the object seen and the surface on which the artist is painting. The artist can see the scene and the canvas at the same time, just like photography
Same as the double exposure in . This allows the artist to transfer key points from the scene directly onto the canvas, which can aid in accurate rendering of perspective. The artist can even trace the outlines of objects in the scene.
This device was only patented in 1806, but Kepler clearly described such a device in his book "Refraction Optics" in 1611.
In fact, those painters who were good at realism from the 16th and 17th centuries probably did not all rely on their craftsmanship. According to research, many great painters, including Caravaggio, probably did not work with bare hands, but used
With the help of optical equipment. Artists at that time already knew that they could use the principle of small hole imaging or directly use the obscura of lens projection to assist in painting.
If the small hole imaging principle is used, a large space is required, and the bright house or tent must be shielded as much as possible. Later, technological improvements used lenses, and the entire camera obscura was smaller, so small that a servant could carry it away. Of course
The camera obscura further developed, and the projection screen or frosted glass was replaced by a negative, and it became the earliest camera. This camera obscura has a specially developed model, which can be used to view distant scenery, which is convenient for field inspections and surveyors. There are also
This kind of projection can directly overlap the drawing paper, so that the painter can directly compare the scenery with his own painting, which is very convenient and accurate. Natural history painters in the 19th and 20th centuries widely used this device to accurately depict creatures.
There is a similar design on the microscope. Biologists who used it to draw microorganisms in the 19th century usually relied on this to draw. For example, they can show the structure of various cells, such as the appearance of various bacteria. This kind of microscopic scene is photographed.
The technique is very difficult to do. The microscope shows a virtual image, which is inherently difficult to image. If you try to make it, the resolution of the photo is also very limited. In contrast, humans can observe the detailed structures under the microscope for a long time.
, after figuring out its specific structure and drawing it directly, the effect will be better.
It is conceivable that since this thing is so useful, it has naturally been put on the agenda of the optical factory early. Not only is it needed for painting museum paintings, but the health department must also be equipped with this equipment if it wants to train qualified health and epidemic prevention personnel.
Fortunately, this thing does not have many technical difficulties, and it is not difficult for optical equipment factories that are already able to mass-produce telescopes, spectacle lenses, and other equipment.
Lin Hanlong was just about to think more about the production of precision measuring tools that he had discussed with Yuan Haowen yesterday, when Cai Junjie suddenly came in.
"Chief, Wang Yuanlao from Nanyang Company is here. He said he wants to talk to you."
"Oh? Is it that Mr. Wang who came yesterday?"
"Yes, that's him."
"Invite him to come to my office."
Lin Hanlong was not too interested in Nanyang Company's affairs, but since the other party was so eager to see him, there must be something important.
A few minutes later, Wang Kai arrived at Lin Hanlong's office.
Strictly speaking, it was not an occasion like a meeting, but it was the first time the two met in private. After the two parties greeted each other and sat down, Lin Hanlong asked casually: "What do you want from me?"
Wang Kai was somewhat embarrassed - to be honest, he didn't know how to say this.
After an awkward silence for a moment, Wang Kai mustered up the courage:
"Let me introduce myself first. I am the development manager of Nanyang Company."
Lin Hanlong nodded to show that he heard it.
"I came to visit you today..." Wang Kai unconsciously used honorifics, "There is something about Sonia... who is your life secretary..."
"What's going on?!" A huge question mark popped up on Lin Hanlong's head.
"That's right," Wang Kai was afraid of causing any misunderstanding, and immediately said that he was about to lead the Southeast Asia expedition plan, and the expedition team needed an experienced naturalist. That's why he thought of Sonia.
"This inspection is very important, so I hope Sonia can also participate in this inspection."
Lin Hanlong's originally nervous face relaxed. Wang Kai's mood also relaxed slightly.
"How big is the scope of your inspection this time, and what area is it roughly? What is the purpose of the inspection?" Lin Hanlong asked with interest.
