Abstract
The implementation of phase shifting interferometry to analyze the Lau inte rferometric fringe patterns is proposed. The fundamentals of this applicati on are theoretically discussed and the basis of the phase map interpretatio n is outlined. The three steps algorithm is used to depict the phase maps o f lens-like test objects and an application for measuring focal lengths of lenses is reported. Experimental results are presented.
