The dynamic photoelastic properties of an epoxy-polysulfied copolymer (epoxy rubber), often used as a photoelastic material, were analyzed by applying an FFT operation system with a device prepared to obtain simultaneously the interrelations between birefringence, stress and strain under various test temperatures and frequencies. As a result of the studies, the complex modulus, complex strain-optical coefficient and complex stress-optical coefficient of the epoxy rubber were determined and master curves presenting the combination of the test frequency and temperature were composed successfully by applying a reduction principle. It was confirmed that the complex strain-optical coefficient was related to dynamic photoelasticity because the coefficient scarcely changed against the frequency compared with the complex stress-optical coefficient.
