ERASABLE REAL-TIME HOLOGRAPHIC OPTICAL STORAGE ELEMENT

CONVENTIONAL HOLOGRAPHIC RECORDING MEDIA DO NOT PROVIDE REAL-TIME WRITE OR ERASE CAPABILITIES. SPATIAL-LIGHT MODULATORS CAN BE WRITTEN AND ERASED IN REAL TIME, BUT CANNOT PROVIDE THE HIGH RESOLUTION REQUIRED FOR HOLOGRAPHIC STORAGE (> 1000 LINES/MM). WE PROPOSE A MAGNETO-OPTIC HOLOGRAPHIC RECORDER (MOHR) CAPABLE OF SUBMICRON RESOLUTION AND FRAME TIMES ON THE ORDER OF 1 SEC/CM(2). THE MOHR MAKES USE OF A MAGNETO-OPTIC LAYER SIMILAR TO THAT USED IN ERASABLE OPTICAL DISK MEMORY. CONFIGURED FOR SERIAL ACCESS, THE MOHR CAN BE USED AS A HOLOGRAPHIC DISPLAY OR AS A HIGH-RESOLUTION, COMPUTERCONTROLLED OPTICAL FILTER. CONFIGURED FOR PARALLEDL ACCESS, THE MOHR IS AN ELECTRONIC REPLACEMENT FOR PHOTOGRAPHIC FILM. OPTRON SYSTEMS' EXPERIENCE WITH THE DESIGN AND CONSTRUCTION OF DIVERSE SPATIAL LIGHT MODULATORS MAKES US UNIQUELY QUALIFIED TO CONSTRUCT THE MOHR.
