Spatial multiplex tomography.
We present a new method for the synthesis of sections of a 3-D object from an encoded record of its projections. This record is prepared by spatially multiplexing selected projections of the original object onto a photographic film. The film is then inserted into a coherent optical analyzing system, where an image of one planar section is generated; only a single plane of object is in sharp focus, while the rest of the object is blurred. The location of the sharp plane may be chosen arbitrarily with no need to recall the original object. Analysis, supported with experimental verification, is presented.
