ABSTRACT:
A variable weight optical interconnector is disclosed to include a projecting device and an interconnection weighting device remote from the projecting device. The projecting device projects a distribution of interconnecting light beams when illuminated by a spatially-modulated light pattern. The weighting device includes a photosensitive screen provided in optical alignment with the projecting device to independently control the intensity of each projected interconnecting beam to thereby assign an interconnection weight to each such beam. Further in accordance with the present invention, a highly-interconnected optical neural network having learning capability is disclosed as including a spatial light modulator, a detecting device, an interconnector according to the present invention, and a device responsive to detection signals generated by the detecting device to modify the interconnection weights assigned by the photosensitive screen of the interconnector.
