Two hours later, Gu Mojie left school and went to the city, found an optical store, and then paid more money to get a pair of coated resin aspheric lenses. The frames are made of titanium, and the temples can be folded in two sections instead of the ordinary one-stage folding. Together with the lenses and shelves, it cost him nearly two thousand dollars.

In the glasses market in 03, the gap between technology and the 2010s is not too obvious, it is nothing more than that the curvature of aspherical lenses is not as superior as that of later generations, and the coating materials are different. In general, the biggest difference lies in the price: high-end glasses in 03 are really many times more expensive than in 13.

This pair of glasses can be regarded as spending all the money that Gu Mojie saved from selling patents and living expenses. However, he also had to spend this money. Because this pair of glasses has a lot to do with his performance as Hatsune Musume.

After being in the optical store for half an hour and getting the things, as soon as Gu Mojie went out, he did not hesitate to remove a part of his left leg from the eye frame, and then threw away part of the detachable shell of Hatsune Niang and inlaid it, which was also in tune.

Hatsune Musume's core processor is actually very small, and there is still some redundancy in the shell space, and some sensors can be wirelessly connected to the core processor, so the structure is very flexible. Later generations like to make the structure of mobile phones like glasses, which is said to be a popular trend that only began to emerge in the late 2030s, but I didn't expect it to fit now.

"Okay, now it's time to start calibrating the holographic projection of the cylindrical lens you want, as well as the 3D coating projection. Let's calibrate the parameters according to this pair of glasses. Gu Mojie lifted his glasses and ordered Hatsune Niang.

Cylindrical lens holographic projection and 3D coating projection are the cheating methods that Hatsune Niang thought of for Gu Mojie.

Compared to motion capture technology, which is currently unusable due to the lack of sensors, these image output technologies are much less demanding, and the projection head of the 2050s is much smaller than the cameras of the 2010s, and the increase in resolution cannot be measured. Although Hatsune Musume travels through time and space in the simplest version, it can still ensure the completeness of the projection hardware.

However, although the technology of cylindrical lens holographic projection is more effective, there is a problem: once this kind of projection is used, it is not only visible to Mo Jie, but also visible to others, so it is obviously not suitable for cheating.

The remaining option is 3D coating projection. This is also a technology that emerged around the 2040s, specifically, it is possible to use the projection head of a personal mobile phone to directly project video information onto the user's eyeglass lenses, contact lens lenses, or even directly onto the retina.

This is a confidential video projection signal that ensures that a single person can see it, and the spectacle lens must be coated with an anti-reflective film, and then the projection head of the mobile phone can correct the parameters according to the material of the anti-reflective film, ensuring that the projected light will produce total reflection on the lens without the slightest transmission, so that no one other than the user can see the spilled light.

"550 nm wavelength positive green light test...... 700 nm wavelength positive red light test...... 400 nm wavelength violet light test...... Calibrated according to the feedback number, it was confirmed to be an anti-reflective coating for 18% zirconia and 82% titanium oxide evaporation process...... Accounting for the ...... of the total reflected light wavelength The accounting result has been obtained, please confirm whether the effect is acceptable. ”

After Hatsune Niang's official voice prompt, Gu Mojie suddenly saw a blue in front of him, and two blue linear cursors appeared on the lenses in front of him, that color was not very comfortable at first glance, but after getting used to it, he could make sure that he could see it clearly.

"Can't you change the color? Can only cast this blue light? Will changing to green protect your eyes? ”

"The green ones are not fully reflective and can be seen by others, although the luminous flux has been reduced according to demand, which is ultimately a risk - anti-reflective coated lenses were originally designed to take advantage of the chemistry of the coating and the precise evaporation thickness of the design to ensure that certain wavelengths of light are not reflected when passing through the lens.

However, according to the basic principles of optical physics, only light with a half-wavelength length equal to the thickness of the coating is the easiest to achieve full transparency. The wavelength of visible light ranges from 350 nm to 700 nm, so the effect of the coating on light anti-reflection/suppression is different for different color wavelengths. Just now I tested the full wavelength reflectance of this lens film, and picked the wavelength with the highest reflectance and the least easy to wear for you, so you can bear with it. ”

was said by Hatsune Niang, Gu Mojie also gladly accepted this setting, after all, secrecy is the most important.

……

Taking a taxi back to school, Gu Mojie found Lu Wenjun to help, took some money, stuffed red envelopes in private, or found a way to find a familiar music teacher for convenience, after all, he had to rent the school's equipment. In order to ensure success, Gu Mojie promised to only use it in the instrument classroom, and never take it out, and it only took two days, and it was checked and accepted by the music teacher after use.

Gu Mojie himself did not come forward in this matter, and Lu Wenjun contacted him, so Gu Mojie didn't know what happened.

Perhaps, Lu Wenjun will use the excuse of the class meeting program to rent these instruments, right? Anyway, it was done, so that Gu Mojie owed her a favor again.

After getting the things, watching Gu Mojie wipes there with a guitar for a while, and then put rosin on the violin bow, Lu Wenjun always felt that this matter was quite unreliable: "Is this really useful?" Are you really planning to practice hard for a day and a half before going on stage? ”

"Don't worry, Junjun, let me figure it out on my own - you see, aren't there all the textbooks here? There is also sheet music. I'm a self-taught person. Today's matter is your love, please have a good meal during the winter vacation. ”

"You're burning your eyebrows, and you're talking about what you don't invite, really." Lu Wenjun felt that he was going to be defeated by Gu Mojie's frankness, why wasn't the other party afraid of messing up tomorrow and being embarrassed? In a depressed mood, Lu Wenjun held his chin with both hands, made a sunflower shape, and muttered:

"Alas, when it comes to delicious food, I sometimes think, if only I were a boy, I would eat whatever I wanted, and I wouldn't have to keep in shape - it's decided, I'll go to self-destruct my image after the college entrance examination, it's best that no one pays attention to me in college, then I can eat whatever I want, and there is no pressure at all~"

It was Gu Mojie's turn to be dumbfounded.

Just to be able to eat delicious food openly, without having to keep in shape, you fantasize about being a man? Is this what a beautiful woman should say?

What he didn't know was that in his previous life, because of the misdiagnosis of SARS in March, he delayed the college entrance examination for a year, missed the 03 year science super difficult paper that could have allowed him to show his talents, and since then he has embarked on a different path. And Lu Wenjun also entered the university, became a "qiē into appetite" academic tyrant bold girl, and later went all the way to graduate school, embarked on the road of no return for a female doctor in a strong engineering school, to the moment before Gu Mojie's rebirth, Lu Wenjun did not find a boyfriend.

Really, Qiantang has been separated for more than ten years, and it is difficult to see Wen Jun in the palm of his hand. I am not famous and unmarried, and I may not be as good as others.

It's a pity that who made his memories of his life experience in the future fly away, so he would still be surprised to hear Lu Wenjun's mouth at this moment.

"Well, what I heard just now must be an illusion, and it must have been opened in the wrong way." Gu Mojie laughed at himself.

Lu Wenjun also slammed under his ridicule, and then jumped up shyly: "Ah! Forget everything I just said! ”

"It's okay, I said it, it must be a hallucination......"

Gu Mojie didn't finish speaking, Lu Wenjun ran away by himself, but he saved Gu Mojie from finding an excuse to drive her when he was practicing. There was only one left in the music classroom, and Gu Mojie was relieved to boldly tune out Hatsune Niang.

"After a while, the cursor is a little bluer, which is where you want to align your left hand at the kneading string. The color block that is more cyan is the amplitude of the right hand to sweep the string, understand? Let's give it a try. If you want to play the score, tell me the name of the piece, and I will compile it directly into a prompt spectrum. ”

"Okay, let's try it." As soon as Gu Mojie's words fell, he saw that in the direction he looked through the lens of his glasses, directly opposite the position of the guitar fretboard, there were small pieces of cursor jumping. He didn't think much about it, so he just pressed it - of course, because he had just adapted, he could only press it simply, and he couldn't knead the strings or make a trill.

Although the cursor is very accurate with every string and frets on the fretboard in Gu Mojie's opinion, he actually knows that these cursors are not really shining on the guitar fretboard, but projected on the lenses of his glasses.

In this way, the performance becomes a "rhythm master" who presses wherever the light is on, and there is a forewarning of the change of light and dark, which is no more difficult than playing a game.

Half an hour, an hour, time passed imperceptibly. Since he doesn't really want to be a master artist, and he won't give others the opportunity to order repertoire, Gu Mojie can of course just pick a few or even one piece of music for each instrument to practice. With the posture of a rhythm master, this kind of thing is not difficult, not to mention that he also touched the guitar and violin before he was reborn.

One afternoon, Gu Mojie first mastered "Hotel California", but it was a non-prelude version. Because the prelude of the original song is a bit flashy, it is difficult to master it thoroughly for the time being, and in front of these rookies in the school, it is enough to kill competitors in seconds without taking the prelude.

The reason why he had to choose "Hotel California" was because he knew that he would definitely not be able to escape the hard indicator of singing English songs at the class meeting. So after solving this hard bone, the latter is much easier to say, and he doesn't care about the style, he just wants to pretend to look stylish enough, and the skills are not too complicated to choose. An excerpt from the piano's moonlight, a second excerpt from the violin's door E, and a ...... from Liang Zhu

By the time Gu Mojie felt a strong hunger attack, the school cafeteria had already closed, and he left the music classroom, locked the door and went to bed alone. Along the way, thinking along the way, tomorrow if you secretly practice for another morning, you should be able to see the moves.
