Abstract: A unique photodichroic readout device composed of photodichroic material u which is passed a circularly polarized light beam that is horizontally or vertically polarized dependent upon the storage of information in the material. The beam is then passed to a beam splitter which segregates the horizontal polarized light and the vertical polarized light. The two individual beams pass to individual detectors whose output is coupled to a difference amplifier. The system also provides a method for selectively storing information within the photodichroic material.
