ABSTRACT:
A method for reproducing an object surface wherein a time succession of spatially encoded different radiant energy patterns are projected at the object surface and records are made of the object surface during such projections from two or more spatially separated locations. The sets of records recorded at the separate spatial locations are then utilized to determine the spatial points on the object surface.
