Projection system for high definition digital images

Abstract

A high definition digital image projection system that uses modulated lasers to project high resolution images at frame rates that are used in the movie industry. An exemplary system employs digital-to-analog converters that convert digital signals derived from an image memory that correspond to predetermined colors that make up an image into analog signals for the respective color. A plurality of lasers 13a, have their light intensity outputs respectively modulated by the outputs of the digital-to-analog converters. A plurality of optical devices such as color sensitive half-silvered mirrors or sets of prisms having color-sensitive coatings on their respective faces, are used to produce a coaxial set of laser beams. First and second rotating mirrors are used to reflect the coaxial set of laser beams and generate an image for viewing. A mirror rotation synchronization circuit synchronizes rotation of the first and second rotating mirrors.
