Abstract
We demonstrate the use of temporal phase unwrapping in combination with wav elength-scanning interferometry. Two unwrapping strategies are considered: fitting to a reversed exponential sequence and complex Fourier-transform ra nging. Measurement of a 10-mu m step by use of an external-cavity laser dio de is discussed. (C) 2000 Optical Society of America OCIS codes: 100.0100, 100.2650, 100.6890, 120.0120, 120.2650, 120.3940.
