| Abstract: | The optical anisotropic problems are transformed into the optical isotropic ones by the method of interpolatatioa A new method of caustics for elasto-optical constants is proposed and, as examples, the elasto-optical constants of plexiglass and Aradite B as well as Polycarbonate are measured using the principle and the method in the paper. At last the results are comparied with that of reference concerned |
