ABSTRACT:
A laser scanning apparatus, and related method, comprising a plurality of optical fiber bundle elements each corresponding to a respective one of three primary colors and having an emitting end, each emitting end being disposed at a constant pitch with respect to the other and aligned in a horizontal scanning direction and emitting a light beam of the respective color, an array of light switches disposed adjacent to the emitting ends of the optical fiber bundle elements, each light switch disposed with respect to the other at a pitch equal to the pitch between adjacent emitting ends. Each light switch independently opens or closes in response to information corresponding to a horizontal scanning period of an input video signal corresponding to a video image. A device for polarizing a light beam passing through the array of light switches at each horizontal scanning period and scans the polarized light beam in a vertical scanning direction to project a video image on the screen.
