ABSTRACT:
An outer product shearing interferometer for an optical source of one-dimensional extent which provides interference between every two points on the source. The interferometer comprises an input plane containing the source, an output plane for observing the outer product, a hologram which imparts the sum of two contributions whose phases are bilinear functions of the spatial coordinates, a two-dimensional Fourier transform system which illuminates the hologram with the transform of light from the input plane, and a one-dimensional Fourier transform system which takes light from the hologram and illuminates the output plane.
