Abstract

We present a fast and robust approach to phase shift registration from randomly phase shifted interferograms. The approach is based on a singular value decomposition followed by an iterative, projection based optimization procedure. Compared to known algorithms it is fast and shows comparable or better registration quality depending on the case of application.
