It's fake. Perspective glasses can't penetrate objects, only some pre-processed playing cards can be seen.
perspective glasses can only penetrate some thin objects, not all of them can. It's actually impossible to see naked people, but it's just to promote this kind of glasses. Now science is not so developed. At present, fluoroscopy technology is mainly used in exploration and medicine, such as B-ultrasound, X-ray machine, CT, nuclear magnetism, etc. These instruments are very expensive. If there is such a fluoroscopy of human body, medicine will develop simpler imaging instruments.
perspective glasses use the principle of far infrared rays. Because the wavelength of infrared light is longer than that of visible light, it can be less reflected by some materials or textile fabrics than visible light, and it can be reflected by objects hidden under the fabric and then pass through the fabric again, so that the fabric can be translucent and similar to transparent clothing, and sometimes it can even form an almost nude effect. Of course, not all clothes can be seen through, and pure cotton is the safest and cannot be seen through by infrared light. Nylon and cotton blended fabrics can achieve the perspective effect, especially in wet clothes in swimming pools and other places.
use of perspective glasses
infrared shooting function can be used to shoot some objects covered by some objects, including shooting objects under the sand through thin sand and shooting altered documents through ink. In fact, these have been widely used in public security criminal investigation.
American m&; The infrared mirrors produced by K Optical Company and Schneider /B+W Company in Germany only let near infrared rays pass through, and block visible light and ultraviolet rays from passing through. With this kind of infrared lens, in the daytime, when the camera is in night shooting mode, it can only see the image reflected by infrared rays, that is, it can see through people's clothes.
perspective conditions
1. The human body emits or reflects some external rays, such as visible light and infrared light, which can penetrate the coat and be received by your glasses.
2. Your glasses can emit some penetrating rays, which penetrate the clothes and are reflected by the other person's body, and then penetrate the coat again and are received by your glasses.
Precautions
If this perspective function is only used for family entertainment and not used in public, it will not be illegal, but if it is used to take perspective photos of others, it will violate the privacy and dignity of others; If taking perspective photos of others for commercial or even other ulterior purposes constitutes a crime, the victim can pursue the legal responsibility of the other party.
