MULTI PRISM MECHANISM FOR THREE DIMENSIONAL IMAGE LASER EXPOSURE SYSTEM AND METHOD

摘要

A multi prism mechanism for three dimensional image laser exposure system comprises an exposure motherboard (1) and a laser control transmission unit (2). The upper part of the exposure motherboard (1) is provided with a multi prism structure (3) a lens (4) an angle switching reflecting mirror (5) an optical detection reflector (6) an optical detection device (7) three acousto optic drive controllers (8) a laser drive control plate (11) multiple supporting columns (9) and a reflecting mirror (10). The laser control transmission unit (2) is fixed on the supporting columns (9) by a nut so that the laser control transmission unit (2) is superposed on the exposure motherboard (1). The lens (4) is provided with an incident surface and an emergent surface. Three parallel laser generating sets (21) are arranged on the laser control transmission unit (2) and each laser generating set (21) comprises an acousto optic modulator (212) a light valve (213) a directional mirror (217) an optical expansion and contraction mirror (214) a laser reflector (215) and a concentration reflector (216). The multi prism mechanism has the advantages of reasonable and simple structure stable performance convenience in use good effect and bright color of printed three dimensional images and the like.
