Abstract : A coherent optical processor device comprised of a monolithic mass of transparent optical material. The device is built up of a plurality of modules, each having a curved reflective surface for performing a Fourier transform operation and a V-shaped reflective surface, for reflecting the beam and directing it to the next module. Plates or masks for changing the amplitude and/or phase of the beam may be inserted in air gaps between contiguous modules. The device provides absolute path length constancy, is not available to the adverse effects of dust, and minimizes the multiple reflections ordinarily produced at air-glass interfaces. (Author)
