The capabilities of optical computers are extended to perform the class of bilinear transformations (of nonzero spread) on 1-D signals. Use is made of the additional degree of freedom in 2-D linear processing. The technique is applied to the study of partially coherent optical systems and to systems in which coherent optical processing is followed by postdetection linear spatial filtering.
