This apparatus provides a means for communicating with an optical recording medium having multiple information storage layers by using spatial light modulators to construct computer generated holograms. The uniqueness of this invention is its simplicity and generality arising from the filter correlation metric optimization technique developed by the inventor. Its importance is the result of the fact that it takes into account the fully complex nature of spatial light modulators to filter incoming light. This technology is highly suited for applications in optical computers, optical storage media, and broad band communications devices. As the market for optical computing devices becomes more prevalent, applications for this unique technology will increase.
Similar possibilities apply to the broadband communications market.
The apparatus can be utilized particularly in holographic video applications for aerospace, robotics, and display. It is also beneficial for long term, high-speed data archiving applications. The spatial modulators can improve training for aerospace operations, commercial products and servicing, robotics, or wherever personnel must be trained for complex or spatial reference familiarization tasks. Development Status A laboratory model of this technology is available for inspection. This technology opportunity is part of the NASA Technology Transfer Program, the goal of which is to stimulate development of commercial applications of NASA developed technology.
