On the Elasto-Optic Constants of Linear Isotropic Dielectrics

This paper presents an analysis of photoelasticity theory as applied to linear isotropic dielectrics. Based on fundamental relations, an expression for the elasto-optic constant as a function of dielectric susceptibility is derived. Formulas for calculating the elasto-optic constant are provided for three phases of dielectrics, relying solely on the dielectric constant. Additionally, the maximum value of the elasto-optic constant for the specified media is estimated.
