Abstract : The paper describes the recent development of an automatic data-collecting-and-interpreting system for a dual-observation method in scattered light photoelasticity. The system incorporates a flexible relay optic, photon-counting, and computer techniques. Photoelastic parameters are evaluated from the photon-counts by means of an electronic digital computer. Evaluation procedures were improved so that the effect of absorption of scattered light is eliminated. (Author)
