The technology for see-through clothes has long been available, but it involves a lot of moral condemnation, is not allowed to be put into the market, and is not recognized by everyone. Just like cloning, cloning technology has long been mature, but cloning is not allowed to be used on humans.
Principle of perspective: General visible light is the light that can be received by the human naked eye (without the help of any external equipment). It is visible light, which is fixed within a frequency range and is light within the frequency. , such as red, orange, yellow, green, blue, indigo and violet, can be directly recognized and accepted by human eyes. However, light outside the frequency cannot be seen by the human naked eye. For example, the light above the frequency is ultraviolet and the frequency below is infrared. This kind of light can only be imaged through equipment and converted into light acceptable to the human naked eye. For example, everyone knows about medical X-rays. This X-ray can not only penetrate people's clothes, but also penetrate people's flesh. After imaging by the equipment, it is converted into X-rays visible to the naked eye.
As long as people appropriately adjust the frequency of the emitter light source so that the frequency can penetrate clothes and reflect images of various organs of the human body, and use equipment to convert them into images that can be recognized by the naked eye, they can see through clothes. But this technology is prohibited from human use and put on the market! They are only used in certain specific occasions, such as security checks, military use, etc. They are see-through clothes.
