Title: The Innovative Contributions of Roy A Cedarstrom
Introduction
Roy A Cedarstrom is a notable inventor based in Fullerton, California. He has made significant contributions to the field of optical technology, particularly in the development of advanced projection systems. His work has been recognized for its innovative approach to light modulation and image projection.
Latest Patents
Cedarstrom holds a patent for a "Two color liquid crystal light valve image projection system." This invention features an optical arrangement that provides color selective prepolarization of light incident upon multiple light valves. The system utilizes a prepolarizing prism to direct light of different polarizations to separate dichroic separators. Each separator transmits an output beam of a single color and polarization state. The resulting beams are recombined by a dichroic adder before being directed to a second polarizing prism. This innovative design allows for effective modulation of brightness and color in projection systems.
