Paper Abstract

Fringe scanning for analyzing shape error of a test surface is performed by fringe shift of interference images with different phases. The method of proposed fringe shift is carried out by a zone-plate, which has fan-shaped sections of four different initial phases of 0, (pi) /4, (pi) /2, and 3(pi) /4. Experimental results agree with the theory.
