Abstract
An imaging system and method directs white light to a reflecting polarizing surface at an angle of incidence substantially equal to the Brewster angle to help maximize or greatly increase the reflected S polarized light and minimize or greatly decrease the reflected P polarized light. A contrast enhancing device also helps to reduce the reflected P polarized light. Color splitter and combining optics devices separate the reflected polarized light into a plurality of different color light components. Light modulating devices modulate each one of the color light components and rotate selectively the S polarized light and direct P polarized light toward a viewing surface. Thus, the output transmitted contrast ratio of the transmittal P polarized light to the transmitted S polarized light is enhanced.
