Abstract
A laser scanning system includes a read light emitting member, a green light emitting member, a blue emitting member, a scanning light member, and a controller. The red, green and blue emitting light members include an optical-frequency modulator and a liquid crystal plate placed between polarized light plates. The polarized light plates are disposed at an angle equal in the polarized light direction. This enables the viewer to use polarized glasses to view a three-dimensional color image on screen produced by the laser scanning system.
