Abstract:

The report is primarily concerned with the precision and pointing at a holographically produced image. After consideration of several possibilities, measurements performed by placing a small self-illuminated dot within the space of the virtual image from the hologram proved to be most feasible. It is shown that images from holograms can be measured by use of a floating dot in a manner similar to that used in mensuration of photogrammetric stereomodels. Simulation studies were performed and indicated that shifts in the reconstruction beam angle of up to 5 degrees could be tolerated. A shift of larger than 5 degrees caused large distortions in the image geometry which could not be removed by a linear transformation. The investigation is in three parts concise discussion of the properties of holography and photogrammetry theoretical imaging characteristics and mensuration. Author
