COMPACT VECTOR-MATRIX MULTIPLIER SYSTEM EMPLOYING ELECTRON TRAPPING MATERIALS

A vector-matrix multiplier in which a matrix is stored in an electron trapping material by exposing the material to visible light passed through a liquid crystal device, which acts as a mask. The visible light raises electrons in the electron trapping material to a higher energy level at the exposed locations. Infrared light is then passed through the liquid crystal device to form an input vector, which is projected onto the electron trapping material. The infrared light releases electrons from the higher energy level, resulting in emission of a pattern of visible light. The emission of visible light from the electron trapping material forms an output representing the product of the input vector and the matrix.
