报道应用偏振光消光法测量光学玻璃材料在强光作用下激发的内部应力分布情况以及用诺曼斯基(Ｎｏｍａｒｓｋｉ)偏振光干涉仪对微小破坏点的测量，结果表明诺曼斯基干涉仪能比较好地分析其破坏进程。

The method of polarized light extinction and Nomarski polarized light interferometer were used to detect the stress profiles and small damage spots optical glass material. Experimental results show that the Nomarski interferometer can help us to analyze the damage process of optical materials fairly well.
