Paper Abstract

A review of our recently developed fringe pattern processing techniques utilizing two dimensional continuous wavelet transform is presented. Their development significantly broadens the range of 2D CWT capabilities. Namely they enable analysis of images containing multiple fringe sets and the carrier fringe contrast reversal. The methods are fully automatic and require no user interference. Their validity and robustness are confirmed using simulations. Furthermore, a novel Talbot interferometer setup utilizing binary amplitude checker gratings with its output fringe patterns successfully analyzed utilizing 2D CWT technique is presented.
