Abstract
This work presents an application of integrated photoelasticity for non-destructive reconstructions of residual stresses in an axially symmetric gradient index (GRIN) optical structure. Transformation of the polarization of light is measured in a plane orthogonal to the optical axis of the article. Stresses are determined within the framework of the Maxwell piezo-optic law (linear dependence of the permittivity tensor on stresses) and small rotation of principal stress axis. This paper generalizes the method of integrated photoelasticity for the case of the curving translucente rays.
