System for forming a quadrifid image comprising angularly related fields of view of a three dimensional object

摘要

A system for generating within a single frame of photographic film a quadrified image including images of angularly, including orthogonally, related fields of view of a near field three dimensional object and characterized by a first subsystem including a plurality of reflective surfaces for imaging a first field of view of the object at one quadrant of the quadrifid image, a second subsystem including a plurality of reflecting surfaces for imaging a second field of view of the object at a second quadrant of the frame and a third subsystem including a plurality of reflecting surfaces for reflectively imaging a third field of view of the object at a third quadrant of the quadrifid image, all of which have identical path lengths to the object photographed.
