Abstract
Official abstract text for this publication.
Several embodiments of projection systems are disclosed that comprise a plurality of controllable emitters, each said emitter providing light for a light path; a plurality of first optical elements, each said first optical element receiving light from one of said emitters; a controllable modulator receiving light from said plurality of first optical elements; a plurality of conduits, each said conduit disposed over a portion of said controllable modulator; a plurality of second optical elements, each of said second optical elements receiving light from at least one of said plurality of conduits, and a controller for sending control signals to said controllable emitters and said controllable modulator. The illumination from the emitters may form a plurality of overlapping areas of illumination upon a projection screen where the image is intended to be formed.
First claim
Opening claim text (preview).
What is claimed is: 1. A projection system comprising: a plurality of controllable emitters, said controllable emitters capable of being locally dimmed according to control signals, each said emitter providing light for a light path; a plurality of first optical elements, each said first optical element receiving light from one of said emitters; one or more controllable modulators receiving light from said plurality of first optical elements; a plurality of conduits, each said…
