Donald K Cohen, Paul J Caber, Chris P Brophy: Rough surface profiler and method. Wyko Corporation, Charles R Hoffman, July 28, 1992: US05133601 (112 worldwide citation)

A method of profiling a rough surface of an object includes moving the object along a z axis so that a highest point of the rough surface is optically aligned with and outside of the focus range of a solid-state imaging array. An interferogram of the rough surface then is produced by means of a two ...
