摘要
An optical processor that can compute the moments of a two- dimensional image in parallel. The image is placed at the plane of a holographic mask which is disposed in the front focal plane of a Fourier- transforming lens and each of the desired moments is found at a respective one of a plurality of photodetectors arrayed in the back focal plane of the lens.
