Abstract
The separable nature of the geometric moment generating functions and the serial raster encoding of the image permits the 2-dimensional moment integral equation to be computed with a cascaded system of 1-dimensional integrations. In this paper new optical processing architectures are presented that use acousto-optic devices illuminated by pulsed sources to enter the data into the optical system. The advanced state of the art of the components used and the flexibility of these architectures can lead to the implementation of practical optical processing system for computing the moments of a real time high resolution image.
