ABSTRACT:
A beam splitter is constructed using one or more cholesteric layers. Each cholesteric layer reflects light of a given wavelength and polarization. The beam splitter is placed in a prism assembly. The cholesteric layers of the beam splitter are chosen such that portions of light entering the beam splitter are individually directed to a specific light path or to a processing face of the prism assembly. A microdisplay is mounted on each processing faces forms a kernel, and each microdisplay processes the light portions (light beams) directed toward them. Light beams reflected from the microdisplays have image content added to them from the microdisplays. The kernel is utilized in a light management system, such as that used in a video projection (e.g., projection television).
