Principle of laser photography map

Laser photography produces images by irradiating the surface of an object with a laser beam. Its working principle is based on the characteristics that the laser beam irradiated by a laser has high energy density and can cause chemical reactions on the surface of photosensitive materials. These chemical reactions will leave a tiny pattern on the surface of the material, which is called Dixon pattern, which is called grating interference pattern. This pattern can contain a large number of small structures as information, which is very useful in recording images. When light falls from the material to the glass plate and is projected onto the screen through the optical device, a visible image is formed.
