Study of Potential Application of Holographic Techniques to Mapping.
Abstract
The potential uses of optical holography in photogrammetric mapping are identified. Techniques are given for presenting information which has been quantitatively extracted by mapping holographic virtual images of realistic objects and terrain. During measurement, with a self-illuminated measuring mark, it was found that the position accuracy varies inversely with magnification and directly as the square of the viewing distance to the image. By modifying the Wild A7 Autograph so that the holographic virtual image could be absolutely oriented it was possible to map the image both digitally and by plotting detailed outlines, planimetry, profiles and contours. It is believed that the first topographic maps ever made from holographic images were produced. (Author)
