【摘要】 考虑了光弹系数的各向异性,对石英晶体中位错双折射象的反衬进行了计算。在实验上采用反射偏光法抵消旋光后沿光轴观察获得了位错双折射象,并和计算结果进行了比较。更多还原

【Abstract】 The contrast of birefringence images of dislocation in synthetic quartz crystal have been calculated with anisotropic elasto-optical coeffficients. Using reflection polarizing microscopy to compensate the natural optical activity, along the optical axis, we obtained the images of edge dislocations and compared it with the calculation.更多还原
