Synthetic formation of defect-free images - by superimposed blurring images of defect on reconstituted multiple perspective images

摘要

A method and arrangement for tomographic synthetic image formation involve passing light through the object (6) from several positions to form perspective images (11) on a recording medium (10). The images are smapled by placing a lens at the source positions so as to superimpose them on a light sensitive layer, thus recording the visual image. The arrangement is designed to produce a natural locking image without defects. The perspective image is partially overlayed by a blurred image derived from the perspective image and of an intensity corresp. to that of the defect present in the image. The blurred image may be conducted by superimposing several visual images lying in front of and/or behind the layer image. This may involve moving the recording medium, lens and/or light sensitive film along the optical system axis.
