Method for producing three-dimensional real image using radiographic perspective views of an object
A sequence of separate radiographs may be made by indexing a radiation source along a known path relative to the object under study. Thus, each radiograph contains information from a different perspective. A holographically-recorded image is then made from each radiographic perspective by exact re-tracing of the rays through each radiographic perspective such that the re-tracing duplicates the geometry under which it was originally prepared. The holographically-stored images are simultaneously illuminated with the conjugate of the reference beam used in the original recordings. The result is the generation of a three-dimensional real image of the object such that a light-sensitive device can be moved to veiw the real image along any desired surface with the optical information in all other surfaces greatly suppressed. 4 claims, 5 drawing figures.
