Optical preprocessor compares 16 incoming signals with reference voltages. Integrated optical substraction to take "vector difference" of two sets of analog voltages. Applications include satellite onboard processing of pictorial data so data not useful discardes; device recognizes presence of accessive cloud cover and signals hault to data transmission.
