摘　　要：采用灵敏色片偏光应力仪和激光电光调制偏光应力仪相结合的方法,研制成大光场、高精度、低应力自动测量仪器,以检测显象管玻壳等透明物体的残余应力。已在显象管玻壳的质量检测中取得良好效果。Combining polariscope with electro optic modulator, an automatic and precise measuring system with large light field is developed to detect residual stress of transparent object. It has been successfully used for quality testing of teletron glass.
