Abstract

We have developed a system for measuring the photoelastic constants of optical films using an optical heterodyne technique generally used to measure birefringence. The system included a compact tension tester and was automated by software. When measuring an optical film used for a liquid crystal display under low stress, which is difficult with conventional measurement techniques, we could determine whether the photoelastic constant was positive or negative and obtained a value of +0.14×10^-12/Pa.
