title: Temporal phase unwrapping applied to wavelength-scanning interferometry.
abstract: We demonstrate the use of temporal phase unwrapping in combination with wavelength-scanning interferometry. Two unwrapping strategies are considered: fitting to a reversed exponential sequence and complex Fourier-transform ranging. Measurement of a 10-microm step by use of an external-cavity laser diode is discussed.
