1. A system for optical real time analog computation by manipulating optical signals in two spatial dimensions simultaneously, including in combination:

  • first and second terminal means for coupling beam signals, respectively, as inputs;

    optical computation means;

    first means for coupling said first terminal means to said computation means as an input;

    second means for coupling said second terminal means to said computation means as an input;

    said computation means having the outputs of said first and second coupling means as inputs and providing a mathematical relationship of its inputs, as an output,said computation means including at least one spatial light modulator (SLM) for recording first input images and for reproducing output images when illuminated by second input images,said SLM including a free carrier source for recording and reproducing optical images by forming charges in potential wells created by applying voltages to electrodes in said free carrier source.
