ABSTRACT:
Color separation and synthesis systems, color separation systems and color synthesis systems, illumination optical systems, projection optical systems, and projection display devices using these systems include a wavelength-splitting element that reflects linearly polarized light of one wavelength and transmits light of another wavelength; a polarization-transforming element that changes the direction of polarization of linearly polarized light of one wavelength and that is arranged adjacent and at least nearly parallel to the wavelength-splitting element; and a polarization-sensitive beam splitter that reflects light having one direction of linear polarization and transmits light with another linear polarization. These systems provide for dividing and combining three linearly polarized light beams of different wavelengths so that they provide imaging beams to and from display elements, such as LCOSs, that can produce a high quality full color image with fewer optical elements in the various systems and the projection display device.
