磷酸铝(α-AlPO4)单晶旋光性的研究
Investigation of optical gyration in α-AlPO4 crystals
摘要
本文研究了磷酸铝单晶的旋光特性.用偏光显微镜观察了晶体的锥光干涉图、埃拉螺旋图;测量了晶体的旋光率、旋光率随波长和温度的变化.指出该晶体旋光性质是受晶体中Al-O及P-O四面体的旋向和随温度的变化所制约.
Abstract
This paper presents the investigation of optical gyration in α-AlPO4 crystals. By polaroids, the gyration light interference pattern and "pa" helical pattern have been observed. The optical gyration rate and its variations with wavelength and temperature have been measured. It is pointed out that the optical gyration of this crystal is constrained by the rotation direction of Al-O and P-O tetrahedron and their variations with temperature.
