Pagination or Media Count:
An optical correlator is disclosed that compares signals of interest against selected reference signals stored in holograms both of which are imaged onto a spatial light modulator comprising electron trapping material. The cooperative action of the light from the hologram and the light from a delayed line causes the spatial light modulator to produce signals that are proportional to the correspondence between the signals of interest and the reference signals.
