摘要
采用内插法将光学各向异性材料的问题转化成准光学各向同性材料的问题,提出了一种用焦散线确定材料弹性光学系数的新方法.以有机玻璃、环氧树脂及聚碳酸脂为例,运用文中所述原理和方法测量了它们的弹性光学系数,并将所得结果与有关资料所给结果进行了比较.
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
