Multiple-aperture three-dimensional image construction utilizing fringe-modulated speckle patterns.
A technique is described for recording and reconstructing two- and three-dimensional color images utilizing a fringe-modulated speckle pattern. A multiple-aperture imaging system generates the modulated speckles and produces an image plane hologram in which the various complex waveforms, passing through the individual apertures, operate simultaneously as object and reference beams. This holographic recording system is considerably less sensitive to external vibration than conventional off-axis holography and requires much less stringent temporal- and spatial-coherence specifications for its light source.
