In this paper, photoelastic problems involving optical activity are analysed using Stokes parameters. A set of differential equations equivalent to the Maxwell-Neumann equations is derived which yields results with greater ease than other currently available methods. A few specific problems are solved by using these equations. A brief discussion on the use of scattered light methods in problems with optical activity is also included.read more

Three-Dimensional Photoelasticity
TL;DR: In this paper, a three-dimensional photoelasticity model was used to evaluate the triaxial stress field of a transparent material with a 3D light path, which is based on the phenomenon of temporary or artificial birefringence.

Optical phenomena in photoelastic models by the rotation of principal axes
TL;DR: In this article, the basic equations of photoelasticity are derived in a form which is simpler than that of equations known previously, using the matrix representation of the solution of these equations, and it is shown that when rotation of principal axes is present there always exist two perpendicular directions of polarizer by which the light emerging from the model is linearly polarized.

TL;DR: In this paper, the results of an investigation and extension of the various proposed procedures and methods of analysis for the photoelastic determination of three-dimensional states of stress are presented, and a true extension to three dimensions is given by the determination of the effect on retardation of appreciable variation in the orientation of the secondary principal stresses in planes perpendicular to the wave normal.
