Abstract

An important application of holographic optical elements (HOE) is coordinate transformations (or mappings) to put data into a format that can be operated on by an optical processor. In optical coordinate transformation, a specific one-to-one mapping of pixel locations in the input plane to pixel locations in the output plane is produced. For some desired transformations, the data redistribution cannot be realized with a single continuous-phase hologram, and in these cases a multiple hologram system must be considered. The processing of spotlight synthetic aperture radar (SSAR) data is used as a sample application to illustrate the concept. The design and fabrication of the holograms for SSAR data processing is discussed and experimental results are given.
