Abstract

This paper presents an approach to extract local frequency and phase of interferogram from the ridge of its wavelet transform simultaneously. The principle is introduced. A Morlet wavelet is adopted for the continuous wavelet transform of interferogram. A numerical simulation and an experimental example have shown to verify the validity of the method introduced above.
