Abstract

One of the powerful approaches to demodulate a single fringe-pattern is the regularized phase tracking (RPT) technique. We present here some modifications in the algorithm, which consist in the addition of the modulation estimation and the modification of the minimization algorithm. With these changes, the RPT technique can be used in the demodulation of non-normalized fringe patterns with significative improvement in the processing time.
