Abstract

In some synthetic aperture systems the data gathered from a single transmitted pulse samples the 3-D frequency space of the object. A 3-D image can be formed by taking a 3-D FT of this data. However, the data are often in a form that allows backprojection techniques to be effi-ciently used to generate the image. We describe an optical hybrid coherent backprojection proces-sing technique that uses a 1-D spatial light modulator, a coherent optical processor, a 2-D detector array, and some simple computer post-processing to produce the image.
