The weakness of the mirror, how not to be found?

Perspective is bullshit. So far, except for X-rays, others, such as infrared, ultraviolet, radar and ultrasonic, have been proved unable to achieve the perspective effect. Laser is the most interesting, the skin will scatter laser, so the effect of laser imaging on human body capture is very poor! The so-called infrared perspective is extremely demanding, only a few materials can penetrate it, and it needs a wavelength above 1000nm, and most infrared sensors at this wavelength are powerless. I have a modified 850 nm infrared camera at hand. I shot countless skirts in the sun, only a few of them can penetrate through the color dye on the skirt, and the contrast of underwear is dark, which is barely effective. In fact, the underwear at that time was directly visible to the naked eye, but the printing interfered. ) The swimming pool is even more sad. The near infrared is greatly disturbed by water, and it is all black, which is far less than what the naked eye imagined. The only thing with a sense of accomplishment is the auto show! Because of the inferior chemical fiber material on the model ~ ~ hehe, but it needs infrared fill light, and it is still very powerful. You can't use the infrared flashlight directly ~ ~ and you will be killed, so all kinds of troubles, in general, girls should not worry about this kind of thing, because perspective is purely a rumor, and boys can stop, by the same token.
