Paper Abstract

A new approach for whole-field digital determination of isoclinic angle and total isochromatic fringe order is presented. The method uses a plan polariscope with two different filters to calculate the photoelastic parameters, and to compensate the influence of the isochromatic fringes on the isoclinic pattern. The method allows for the determination of whole-field fringe orders without zero-order fringes.
