Chapter 2439 Persuasion

"Metrometry in the old time and space is divided into ten categories. I think the mechanical industry relies on two of them, 'geometric measurement' and 'mechanical measurement'. Among them, geometric measurement relies heavily on your optical equipment. For example, Michelson interferometers, after all, optical The measurement method is highly accurate!"

Only then did Lin Hanlong understand why Yuan Haowen was so enthusiastic about him.Then he continued the topic and said: "Michelson interferometer is not too difficult to make, but I don't know anything about the 'measurement' you mentioned, I'm afraid you won't be able to use it after making it." I am in charge of mechanical processing, and I still have interferometer data for measurement in the old time and space, which is a brand new field."

The two had a good time talking about metrology, especially some issues about measuring tools and precision tools.This talk talked about late at night.

It was already midnight when Lin Hanlong returned home from Yuan Haowen.Cai Junjie sent 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 monkey bastard, 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, even though I'm not your wife, the teachers have opinions..."

"If you have an opinion, you have an opinion. If you have an opinion, you will not live?" Lin Hanlong waved his hand, "Don't be so wordy, go back quickly."

"What time will I pick you up tomorrow?"

"Seven in the morning."

"It is too early……"

"roll!"

Cai Junjie wanted to persuade him again, but thinking that his master had such a temper, he simply stopped talking and took the coachman away.

When Lin Hanlong returned home, the light in the hall was still on, and the room was already silent.Lin Guanyu used to wait for him in the hall, but he didn't come home every day, and sometimes he would let her wait on the chair all night.Lin Hanlong felt sorry, so he stipulated that he would not have to wait for him to go home after ten o'clock in the evening, and the family could do what they wanted.

He looked towards the inner corridor, the doors of the room were closed, and it was pitch black.Everyone is asleep.Recently, my daughter sleeps more comfortably at night, and she doesn't make any fuss anymore.Lin Hanlong wanted to visit his daughter, but when he thought that she and Sonia were both fast asleep, he would inevitably disturb him if he went in, so he decided not to go.

After washing up, he rested in his studio—because he didn't come home on time, no one would be happy to sleep soundly in the middle of the night and suddenly someone climbed into bed.So after the house got bigger, he built a studio for himself, and put a small bed in it.Rest here when you come back late.

After this sleep, he fell asleep until it was broad daylight. Lin Hanlong looked at his watch and it was already 06:30.Get up quickly and wash your hands.Here Lin Guanyu has already made breakfast and is waiting for him to eat.

"Still asleep?" Lin Hanlong asked.

"Well, still asleep." Lin Yuyu said in a low voice, "There was another commotion when the sky was about to dawn."

"That's right," Lin Hanlong said, "I didn't hear anything."

"Of course you didn't hear anything." Lin Yuyu said with a slight complaint, "You can hear you snoring outside the door." As he spoke, he began to serve him porridge.

"It's so loud?" Lin Hanlong couldn't believe it, "Then I have to go to the hospital to have a look."

"Snoring also needs to be seen by the doctor, and the doctor must not laugh at you."

"You don't understand." Lin Hanlong was slightly regretful. If it was Sonia, she would definitely explore why she needs to see a doctor for snoring, and then initiate a discussion about breathing and human body structure.

In fact, Lin Yuyu is very similar to some of his elders and relatives. He has a gentle temperament and cares about his family meticulously, but he has no culture.She always relies on the experience she has accumulated over the years and the teachings of people in her previous life to act.Although it feels very warm and appropriate, it is impossible to communicate in depth.

"I don't understand, I don't understand, you can find out who you are!" Lin Yuyu became a little angry, put a basket of steamed dumplings heavily on the table, turned around and was about to go back to the kitchen.

Lin Hanlong grabbed Lin Yuyu's waist and said with a smile (one hundred thousand words are deleted below),... Then he got up calmly, straightened his clothes, and ordered: "Don't leave me a meal tonight, I guess I have work to do." .”

Lin Yuyu nodded silently, stroked her hair again, and asked, "Is my hair all right?"

Lin Hanlong touched her head and said with a smile, "It's not messy at all."

After all, he put on his satchel and went out the door.But Cai Junjie and the coachman were already waiting outside.When Cai Junjie saw Lin Hanlong coming out, he rushed up to greet him, and said, "Master, it's almost 07:30..."

"Didn't you say yesterday that it was too early to pick you up at seven?"

Cai Junjie was at a loss for words, thinking that this is what you said!But he didn't dare to refute, so he complained: "But the pass I applied for the driver is only available until 07:30..."

"Then let's hurry up." Lin Hanlong was in the right mood, and sat on the Venus Zero, slammed on the foot bell, "Let's go!"

When Lin Hanlong went to the optics factory, he inspected the workshop as usual and checked the production records of the night shift.They also randomly inspected a few products produced by the night shift last night.The authenticity rate is rising every month, and our industrial upgrading is still effective.he thinks.

"Has the prototype of the projection plotter been made yet?" he asked Cai Shengjie.

"Five units have been made, and a few more are being assembled and tested."

"Tell them to hurry up, the museum is waiting for use." Lin Hanlong thought helplessly, since Sonia went to work in the museum, the remote exploration team often came to "open the back door" when applying for equipment, "You can test it yourself if you do it well."

"Yes." Cai Shengjie knew that he valued the "user experience" of these devices.

A projector is an optical instrument used to help artists paint.A kind of optical superimposition of the seen object and the surface on which the artist paints is performed using the lens.The artist can see the scene and the canvas at the same time, like a double exposure in photography.This allows the artist to transfer key points from the scene directly onto the canvas, which can aid in the accurate drawing of perspective drawings.Artists can even trace the outlines of objects in the scene.

This device was not patented until 1806, but it was clearly described by Kepler in his book Refracting Optics in 1611.

In fact, those painters who were good at realism from the 16th and 17th centuries may not all rely on craftsmanship.According to research, many great painters, including Caravaggio, probably did not work with bare hands, but with the aid of optical equipment.Artists knew at that time that they could use the principle of pinhole imaging or directly use the camera obscura of lens projection to assist in painting.

If the principle of pinhole imaging is used, the space required is very large, and it is necessary to cover the bright house or build a tent as much as possible.Later, technology improved and lenses were used, and the entire camera obscura became smaller, so small that a servant could carry it away.Of course, the camera obscura was developed later, and the projection screen or frosted glass was replaced with negative film, and it became the earliest camera.This camera obscura has a specially developed model, which can be used to watch distant scenery, which is convenient for field inspection and survey personnel.There is also a design where the projection can be directly overlapped with the drawing paper, so that the painter can directly compare the scenery with his own painting, which is very convenient and accurate. Naturalist painters in the 19th and 20th centuries widely used this device to accurately depict living things.

There is a similar design on the microscope, which biologists used to draw microorganisms in the 19th century generally relied on this to draw.For example, the structure of various cells, such as the appearance of various bacteria.This kind of microscopic scene is very difficult to achieve with photography.Microscopes show virtual images, which are inherently difficult to image.The resolution of the photo is also limited if you manage to get by.In contrast, humans can observe the detailed structure under the microscope for a long time, figure out its specific structure and draw it directly, and the effect is even better.

It is conceivable that since this thing is so useful, it was naturally put on the optical factory's agenda early on.It is not only needed for drawing natural history paintings, but the health department also needs to be equipped with this equipment if it wants to train qualified health and epidemic prevention personnel.

Fortunately, there are not many technical difficulties in this thing, and it is not difficult for optical equipment factories that have been able to mass produce telescopes, spectacle lenses, and other equipment.

Lin Hanlong was thinking about the production of precision measuring tools that he had talked with Yuan Haowen yesterday, when Cai Junjie came in suddenly.

"Boss, Mr. Wang Yuan from Nanyang Company is here, and he said he wants to talk to you."

"Oh? Is that old Wang Yuan who came here yesterday?"

"Yes, it's him."

"Ask him to come to my office."

Lin Hanlong was not very interested in Nanyang Company, but since the other party was so eager to see him, there must be something important.

A few minutes later, Wang Kai came to Lin Hanlong's office.

Strictly speaking, it wasn't considered a meeting or something like that, and 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 can you do with me?"

Wang Kai was somewhat embarrassed—to be honest, he didn't know how to say this.

After a moment of embarrassing silence, Wang Kai mustered up his courage:
"Let me introduce myself first. I am the manager of the development department of Nanyang Company."

Lin Hanlong nodded to show that he heard it.

"Come to visit you today..." Wang Kai unconsciously used honorifics, "There is something about Sonia... your life secretary..."

"What's the matter?!" A huge question mark appeared on Lin Hanlong's head.

"That's it," Wang Kai, afraid of causing any misunderstanding, immediately said that he was about to host the Southeast Asian expedition plan, and that the expedition team needed an experienced naturalist.That's why I thought of Sonia.

"This expedition is very important, so I hope Sonia can also participate in this expedition."

Lin Hanlong's originally tense face relaxed.Wang Kai's mood also relaxed slightly.

"What is the scope of your investigation this time, and what area is it? What is the purpose of the investigation?" Lin Hanlong asked with interest.
