ABSTRACT:
First and second lenses are spaced apart in a common plane and provide respective first and second recorded representations of radiant energy issuing from an object surface point or region. The first representation is displaced relative to the second in measure depending on such lens spacing to spatially locate the image location of the object surface point relative to the second lens. With lens focal length known and magnification now determinable, object surface point distance outwardly of the lens common plane may be computed. Since the ray from the image location to the second lens node is also spatially located, the object surface point spatial location is defined.
