Abstract : The goal of this project is the development of techniques that will permit integrated optical devices to be used in inherently nonplanar optical information processing architectures. As a first demonstration of this method an integrated optical synthetic aperture radar processor is being developed. More general image processing operations are achievable in integrated optics form using the time and space integrating processing method. An architecture is presented that can perform an arbitrary linear transformation on an image provided the transformation has a kernel that is separable in the two coordinates. The possibility of photorefractively recording in the waveguide the signals that are necessary to specify the linear transformation using control beams that are external to the plane of the waveguide is explored. Initial experimental demonstration of this idea is reported and an integrated optical vector matrix multiplier that is based on this concept is proposed. Keywords; optical images.
