Abstract
Results of the application of wavelet transform for signal processing in white-light interferometry are reported. The mother wavelet frequen cy is chosen to be the Light-source correlogram 1's, and accurate phas e measurements are obtained from simple correlation computations. The fringe envelope is also addressed and permits a complete analysis of c oherence-limited fringe patterns. Miscalibrations of phase shift and m ean wavelength are also considered.
