摘要
An optical signal processor which employs a coherent light source, two spatial light modulators and a beam splitter. Light is from the source is reflected from the beam splitter and sent to a first spatial light modulator, then sent through the beam splitter, a Fourier transform is performed and the transformed light is then reflected from the second spacial light modulator. The light form the second spacial light modulator is then inverse transformed and returned to the beam splitter where it is reflected to a readout detector. The signal read out is the correlation map between an input image from the first modulator and a filter image of the second modulator.
