用MeF3金相显微镜研究LiNbO3晶体的光像
Investigation on optical patterns in LiNbO3crystal by MeF3metaloscope
摘要
用MeF3金相显微镜观察了多畴和单畴的LiNbO3晶体的X、Y、Z切面的蚀像和光像.发现各切面光像形态与各切面的蚀像形态对应,并与晶体的对称性完全一致.利用晶体的光像确定晶体极性和晶轴是一种简便的光学方法.
Abstract
The optical patterns on X,Y,Z sections of LiNbO3 crystal have been observed by using MeF3 metaloscope. It is found that the forms of the optical patterns correspond to that of the etching patterns, and are identical with the crystal symmetry. It is a simple and conveniently new method by using the optical patterns to determine the axis and polarity of LN crystal.
