Paper Abstract

Although photo elasticity technique has recently become sufficiently refined due to use of digital image processing, the difficulties with an appropriate accuracy, especially in integrated photo elasticity still persist. Specifically, there remain as problem with a precise imaging of three optical parameters describing a general 3D model in the regions, where mutual interference of these parameters leads to deteriorated accuracy. In this paper it is shown how to improve imaging accuracy of PSA Fourier polarimetry method, recently suggested for use in integrated photo elasticity. This can be overcome by incorporation of a compensator into the polarimeter arrangement. Use of the compensator provides equally precise imaging of birefringence through the whole possible range of phase and ellipticity angle values. Also, it allows for determining a sign of phase.
