RT Journal Article T1 Isochromatics demodulation from a single image using the regularized phase tracking technique A1 Quiroga Mellado, Juan Antonio A1 Servín Guirado, Manuel AB In this work we propose a robust fringe demodulation technique applied to the analysis of a single isochromatics fringe pattern produced in photoelasticity. The method used is a regularized phase tracking algorithm with a new sequential scanning technique specifically adapted for the characteristics of the isochromatic fringe patterns: possible apparition of closed fringes, large dynamic range in its spatial frequency content and low noise. The performance of the method is discussed and experimental results are presented. PB Taylor and Francis Ltd.
