  • Patent number: 4703994
    Abstract: A system and method for automatically fabricating multi-hologram optical elements. Signal and reference beams are formed and directed along separate paths that intersect at a recording medium; and a gate is moved through a first sequence to expose a plurality of views, one at a time, to the signal beam to spatially modulate that beam. A matrix of beams, each of which converges toward a different area of the recording medium, is generated from the spatially modulated signal beam, and a mask is moved through a second sequence to pass the matrix beams onto the recording medium to record a plurality of diffraction patterns thereon.
