Abstract

We describe a mathematically-rigorous easy-to-use portable topographical mapping technique that within seconds or less can determine the heights of a surface at 16,000 (128x128) distinct sample points. The necessary data derive from (narrow-optical-bandpass) TV images of a surface which has been illuminated and space-coded by a rapid sequence of laser-projected dot patterns.
