Optical system to compute intensity moments: design.
A frequency-multiplexed coherent optical processor is described that can compute the intensity moments of a gray-scale input image. The space-bandwidth product and dynamic range of the system's components are discussed. A major feature of the system is the ability to operate easily on its outputs to obtain bipolar moments and to correct for various component errors, nonlinearities, and nonuniformities.
