Abstract
A color management system for use with projection displays includes a beamsplitter positioned to receive a light beam, a microdisplay positioned to receive the light beam from the beamsplitter and emit a modified light beam to the beamsplitter, and a plurality of prisms positioned to receive the modified light beam from the beamsplitter and emit a light output that compensates for an optical aberration induced by the beamsplitter.
Claims22
A color management system, comprising:
- a beamsplitter positioned to receive a light beam;
- a microdisplay positioned to receive the light beam from the beamsplitter and emit a modified light beam to the beamsplitter;
- and
- a plurality of prisms positioned to receive the modified light beam from the beamsplitter and emit a light output that compensates for an optical aberration induced by the beamsplitter.
1 more element
An optical system, comprising:
- a first beamsplitter positioned to receive light from a light source and separate the light into a first light beam and a second light beam;
- a second beamsplitter having a first portion positioned to receive the first light beam and a second portion positioned to receive the second light beam;
- a first microdisplay positioned to receive the first light beam and emit a first modified light beam having first spatial information;
- a second microdisplay positioned to receive the second light beam and emit a second modified light beam having second spatial information;
- a light combiner positioned to receive the first and second modified light beams and emit a light output;
- and
- a plurality of prisms positioned to receive the light output from the light combiner and emit a compensated light output that compensates for an optical aberration induced by the light combiner.
4 more elements
An optical system, comprising:
- a beam director positioned to receive light from a light source and emit a light beam;
- a microelectromechanical system (MEMS) display positioned to receive the light beam and emit a modified light beam to be received by the beam director;
- and
- a plurality of prisms positioned to receive the modified light beam and emit a light output that compensates for an optical aberration induced by the beam director.
