Abstract

A laser projection system suitable for use in commercial motion picture theaters and other large scren venues, including home theater, uses optical fibers to project modulated laser beams for simultaneously raster scanning multiple lines on the screen. The emitting ends of the optical fibers are arranged in an array such that red, green and blue spots are simultaneously scanned onto the screen in multiple lines spaced one or more than one scan line apart. The use of optical fibers enables the scanning of small, high resolution spots on the screen, and permits convenient packaging and replacement, upgrading or modification of the system components. The simultaneous raster scanning of multiple lines enables higher resolution, brightness, and frame rates with available economical components. Alternate embodiments are disclosed to illustrate the flexibility of the system for different optical fiber output head configurations and for different types, sizes, and arrangements of laser, modulation, and scanning components.
