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.
