Digital photoelasticity allows to evaluate the stress field in loaded bodies. There, load stepping method by Ekman and Nurse allowed to avoid inconsistencies and ambiguities. However, it did not become popular by needing six images from two polariscope configurations a three load steeps. This paper updates the conventional method by introducing a polarizer array camera into a circular polariscope. Hence, polarizations of 0° and 90° from a Baumer VCXU50MP camera conduced to bright, and dark field images, simultaneously.With this work, the stress field can be evaluated by using a single optical configuration into the load stepping method.
