OPTICAL SYSTEM DESIGNS FOR GENERATION OF LIGHT FIELDS USING SPATIAL LIGHT MODULATORS

摘要

In described examples, a method of creating multiple light images uses spatially-separated light sources, arranged in an array, operated in multiplexed fashion, for driving a spatial light modulator. Each of the light sources is time-sequenced to direct light at the spatial light modulator during a predetermined time interval. The spatial light modulator is synchronized with the light sources and controlled to produce a desired image during each time interval. The resulting images are received by an optical lens system to provide light images along an image plane. Alternately, the optical lens system focuses the modulated light images on a hogel plane to produce a light field. The pixel count of the spatial light modulator is effectively multiplied by the number of light sources. Each light source may sequentially provide multiple colors to produce a full-color image. The light source array may, in turn, be driven by one or more remotely-located master light sources.
