Paper Abstract

A volume holographic correlator (VHC) can function as an optical processing unit (OPU). With its multi-channel processing ability, the VHC is capable to extract inner products between the target image and all the stored remote sensing images with high speed and high parallelism. An opto-electronic hybrid system based on the VHC for scene matching is proposed. The innovative hybrid processing mode of the system combines the advantages of the high parallelism in VHC with the high flexibility and accuracy of digital processing, improving the overall system performances. The influences of the VHC’s unique multi-channel parallel processing ability on the system speed and accuracy are theoretically studied in the context of different VHC working modes. The improvements of the system adaptability for different situations, such as illumination conditions and noise, are also analyzed by numerical simulation. Finally, experimental results are discussed to evaluate the system feasibility.
