AB In this work we propose a robust fringe demodulation technique applied to the analysis of tricolour isochromatic fringe patterns produced in photoelasticity. The method used is a regularized phase tracking (RPT) algorithm, which takes into account the different information contained in the three bands of the colour image obtained with an RGB-CCD camera. Automatic determination of the zero-order isochromatic and the area of interest, the use of a discrete fluorescent illumination and the use of the RPT configures a robust method for automatic demodulation of isochromatic fringe patterns. The performance of the method is discussed and experimental results are presented.
