In research of photoelasticity, photoelastic fringe patterns are obtained through a circular polariscope with different optical arrangements and they are processed with image processing techniques in a personal computer. Image processing techniques are reviewed and discussed for stress analysis of the photoelastic fringes in this paper. The image processing techniques include fringe sharpening, fringe multiplication, and 8-step phase measuring technique. Gradient descent process is used for fringe sharpening. In fringe multiplication, fringes are multiplied twice for limited fringe order. 8-step phase measuring technique is used to separate isoclinics and isochromatics. The results of image processing techniques show that they are quite useful for stress analysis in photoelasticity.
