  • Laser printing apparatus and method for colour dynamic image
    Patent number: 10137717
    Abstract: A laser printing apparatus and method for a color dynamic image are provided. The laser printing apparatus includes an optical system and a recording material; the recording material includes a refraction layer formed by multiple microspheres or microlenses, and a shading layer formed on a focal plane of the multiple microshperes or microlenses; the optical system includes a laser and an graph generator, a laser light emitted by the laser irradiates onto the recording material after being processed by the image generator, the laser light irradiating onto the recording material is focused on the shading layer via the refraction layer, and a focus point is formed on the shading layer when energy of the focused laser light is greater than an evaporation threshold value of the shading layer.
