A DUAL-OBSERVATION METHOD FOR DETERMINING PHOTOELASTIC PARAMETERS IN SCATTERED LIGHT,

Abstract

A dual-observation method is developed for determining photoelastic parameters of objects in scattered light. Using this method, the intensities of scattered light along two directions of observation, making an angle of 45degrees in a plane normal to the beam, are recorded simultaneously without rotation of either the beam or the model. Photoelastic parameters are evaluated from these records. The theory of the method, the apparatus and techniques, as well as illustrative experiment are reported. (Author)
