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...http://www.google.es/patents/US5523881?utm_source=gb-gplus-sharePatente US5523881 - Optical correlator using light phase modulation and two reflective spatial light modulators
