Optical processor using an original display having pixels with an aperture ratio less than that for pixels in an operation pattern display

摘要

A optical processor facilitates the alignment between an original image and transformation patterns, thus improving the operation accuracy, and, if a fixed transmission mask is to be used, facilitates the fabrication of the fixed transmission mask. The optical processor includes an original image display to display an original image and a pattern display to display the patterns for a transformation on the original image displayed on the original image display. In the optical processor, the original image display is os made as to have pixels with a smaller aperture ratio than that of the pixels of the pattern display.
