Abstract:

PROCESS WHICH INCLUDES RECTIFICATION OF A NUMBER OF AERIAL PHOTOS, AND SUBSEQUENT HOLOGRAPHIC RECORDING OF THE PHOTOS. The multi-viewpoint stereogram is useful for viewing scenes in which features are obscured when viewed from certain directions. The second method developed provides a 3-D holographic stereo-photo-pair display viewable in incoherent illumination. The two-viewpoint stereogram is produced by multiplexing right and left eye views on a focused-image hologram plate. Production is relatively simple, but depends upon efficient phase-type holographic material with good clarity. Major advantages of this stereo-pair display over other devices, such as stereoscopes, are the inherent ease of viewing and the possibility of viewing without any auxiliary equipment in improvised illumination.
