Memory glass - give it everything you can't remember.

it's difficult to tell the difference between it and ordinary glass just by comparing its appearance. However, it has an amazing "memory" and can keep an unbroken record of what happens around it. Unlike traditional electronic tools, the way of recording is to complete the memory of things through the change of internal memory molecular arrangement. When the memory needs to be read, a special translation machine can be used to translate the molecular language into images for display

principle

cover a piece of paper with words and images on a transparent glass, and then use short wave ultraviolet, X-ray γ When the X-ray carries out high-energy electromagnetic radiation, the glass can automatically "memorize" these words and images. When illuminated by long wave light sources such as sunlight, the glass preserved in a dark background can still reproduce words and images

research

the extruder has recovered a good momentum in export.

as early as 1996, physicists at Harvard University in the United States envisioned writing information into a durable, glass like transparent material. Glass can resist high-temperature baking, chemical corrosion and mechanical damage, and even has bulletproof function. Scientists have really made great efforts to realize this idea. It is not that glass is difficult to make, but that the laser beam is difficult to control accurately. If you don't pay attention, there will be errors in the tiny patterns carved. Fortunately, this problem has been solved. As soon as a Japanese company heard of this achievement, it could not wait to seize the opportunity. Chairman Wu Xian first extended a warm welcome to the leaders and guests attending the ceremony; For a long time, it is necessary to use this technology to keep the instrument clean, complete parts and accessories, and safe for fused silica (a glass like material), develop new information storage products, and plan to put them on the market in the next few years

British physicist kaczanski is also interested in this technology. He considered whether he could carve a mark on quartz with five kinds of information at the same time, that is, not only reflect the changes in three-dimensional space (length, width and depth), but also record the intensity and polarization of the incident laser pulse. In this way, the information storage density is 8 times higher than that of the Japanese company. It can store trillions of bytes of information on the nail size quartz material, that is, it can store 5million books of 100000 words each. It can almost cram a large library into two "nails". Moreover, based on the test results, kazansky speculated that the information stored in this material can withstand the high temperature of 1000 ℃, can escape the damage of nuclear explosion, and can be safely preserved for 10billion years. Its life is almost coexisting with the universe, and the sun and moon shine together

function

after the memory glass technology is put into practical application, the police can track the whereabouts of the criminal several years ago in one "nail". In addition, the meteorological observatory can track the changes on the earth in the "fingernail". Future humans and even aliens can also use this technology to understand the living conditions of our generations and gradually become popular in the international market with excellent cost performance

after the "light storage" technology is further mature, the application prospect of this kind of glass in the high-tech field is limitless
