MENSURATION ASPECTS OF HOLOGRAMS

THE MENSURATION OF HOLOGRAMS IS FEASIBLE FOR CLOSE UP APPLICATIONS WHERE THE OBJECT IS STATIONARY. A WILD A7 PLOTTER IS ADAPTED FOR MEASURING HOLOGRAMS THROUGH THE APPLICATION OF A FIBER OPTIC TO PRODUCE A MEASURING MARK. POINTING PRECISIONS OF 0.003 INCHES IN X AND Y (PARRALLEL TO THE HOLOGRAM) AND 0.012 IN Z WERE OBTAINED FROM DIRECT UNAIDED VIEWING OF THE HOLOGRAPHIC VIRTUAL IMAGE. SIMULATION STUDIES, VERIFIED BY LABORATORY MEASUREMENTS, SHOW THAT DISTORTIONS DUE TO DEVIATIONS IN THE RECONSTRUCTED BEAM OF UP TO 4 DEGREES ARE SUFFICIENTLY LINEAR TO BE TREATED BY A 7-PARAMETER CONFORMAL TRANSFORMATION. THE GENERAL POTENTIAL AND APPLICATION OF HOLOGRAMS FOR MAPPING ARE RELATED TO THE QUALITY OF THE HOLOGRAM AND TO THE APPLICATION OF PHOTOGRAMMETRIC OPERATIONS TO IT. /AUTHOR/
