Laser printing device and method of colored dynamic graph

Abstract

The invention discloses a laser printing device and method of a colored dynamic graph. The laser printing device comprises an optical system and recording materials; the recording materials comprise a refraction layer and a shading layer, wherein the refraction layer is formed by a plurality of microspheres or micro lens and the shading layer is formed on a focal plane of the plurality of microspheres or micro lens; the optical system comprises a laser and an image generation device; the laser sent from the laser irradiates on the recording materials after being processed through the image generation device; the laser which irradiates on the recording materials is focused on the shading layer through the refraction layer; a focus point is correspondingly formed on the shading layer when the energy of the focused laser is larger than an evaporation threshold value of the shading layer. The different positions of laser focus points are formed on the focal plane of the recording materials through the deflection of the laser beam incident angle through the laser printing device of the colored dynamic graph to implement the heat accumulation of different pigments and the deflection of the incident angle is repeated to form the multi-channel colored graphic laser printing so as to form the representation of a colored multichannel dynamic image eventually.

Description

technical field [0001] The invention relates to the technical field of laser printing, in particular to a laser printing device for color dynamic images and a corresponding printing method. Background technique [0002] Dynamic images and three-dimensional imaging can be realized through microlens array imaging technology. Specifically, a layer of microlens array is first attached to the laser recording material, and then a projection imaging system generates an image above the microlens array, and the microlens array images the recording material under the lower focal plane of each microlens. The recorded information is reproduced in space by the microlens array. With different observation positions, the reproduced image has a dynamic effect. [0003] The existing laser marking technology can form ablated images or characters on the surface of materials through the photothermal effect of the laser focus point on various substrates. This way the image or question is flat a...
