3D Radiograph Display by Means of Halography.
Abstract
Conventional X and neutron radiographs used in the NDT of munitions are essentially two dimensional shadowgraph projections. In many cases a stereoscopic 3D display of an x-rayed item would provide additional information to the radiographer. Although direct x-ray holography is not technically feasible it is possible to create such displays by the proper application of optical holography to previously radiographed items. Several items were x-rayed from different perspective angles and the radiographs were then multiplexed onto one hologram plate. Results yield good three dimensional x-ray views of the object. Exaggerated perspective such as seeing 180 degrees view of the item with a 90 degrees motion of the observer is also possible. An interesting fringe benefit is the storage of large numbers of 12 x 16 inch radiographs onto a small 4 x 5 holographic plate resulting in a storage density improvement of at least 100. (Author)
