Abstract

See full text

A stereoscopic digital projection system for projecting a stereoscopic image including a left-eye image and a right-eye image, comprising: first and second light sources providing corresponding first and second light beams having spectrally-adjacent, substantially non-overlapping spectral bands falling within a single component color spectrum; a spatial light modulator having an array of pixels that can be modulated according to image data to provide imaging light; illumination optics arranged to receive the first and second light beams and provide substantially uniform first and second bands of light; beam scanning optics arranged to cyclically scroll the first and second bands of light across the spatial light modulator; a controller system that synchronously modulates the spatial light modulator pixels according to image data for the stereoscopic image; projection optics for delivering the imaging light from the to a display surface; and filter glasses for a viewer.
