Abstract
Abstract An optical processing system which performs a general matrix transformation. Analog data to be transformed is entered as a first set of inputs written upon a first writing medium in the form of diffraction-grating lines in a column arrangement of a plurality of resolution elements. The matrix transform function is entered as a second set of inputs written as diffractiongrating lines on a second writing medium in a column, row arrangement of resolution elements. With respect to said first and second sets of inputs, magnitude information is contained in the transmissivity of the resolution elements, and phase information may be contained in the spatial frequency of the grating lines. A matrix processing of said first set of inputs by said second set of inputs is optically performed by imaging spatially filtered light from individual resolution elements of the first medium upon corresponding rows of resolution elements of the second medium by means of a first anamorphic telecentric lens arrangement, and by imaging spatially filtered light from the resolution elements of the second medium as a single row of resolution elements in an output image plane by means of a second anamorphic telecentric lens arrangement.
