Abstract:
A laser video projector, comprising:a light source for outputting a beam of white light formed of first, second, and third main wavelengths; light separating means for separating the beam of the white light into beams of monochromatic lights having first, second, and third main wavelengths in a predetermined transmission factor and a predetermined reflectivity; an optical system for making the laser beam of the white light emitted from the light source a parallel beam and controlling the width of the parallel beam on a light path between the light source and the light separating means light modulating means for modulating the beams of the monochromatic lights according to a chrominance signal; light combining means for combining the monochromatic lights modulated by the light modulating means into a beam; and light scanning means for scanning the combined beam of the modulated monochromatic lights, thus forming an image.
