ABSTRACT:
A color management system for use with projection displays includes, for example, a separating polarizing beamsplitter, a compensating prism group, an image assimilator, and a combining polarizing beam splitter. In accordance with an exemplary embodiment, the separating polarizing beamsplitter receives a bi-oriented light input and separates it into two output beams, one comprising a first component and the other comprising a second component. The image assimilator receives an output light beam from the separating polarizing beamsplitter, transmits the light output to one or more corresponding microdisplays, receives one or more modified outputs from the microdisplays, and emits an output comprising those modified outputs to a combining polarizing beamsplitter. The compensating prism group receives from the separating polarizing beamsplitter the other output light beam, transmits it to another corresponding microdisplay, receives from the microdisplay a modified light output, and transmits it to the combining polarizing beamsplitter be combined with the light output from the image assimilator. The compensating prism group may be configured to compensate for an optical aberration induced by the light separator.
