摘　　要：利用特制磁控棱镜型液晶盒构建物理光学双折射实验系统,以分光仪为实验平台测量折射角,用于辅助光的偏振与晶体光学教学.实验现象直观明显,测量数据准确可靠.Using a specially-made magnetism controlled prismatic liquid crystal cell, a novel birefringence ex- periment system of physical optics is developed. On the experimental stages, the refractive angles are measured by a spectroscopy. The device is suitable for the teaching assistance of polarization and crystal optics. The experimental phenomena can be observed easily and the measurement is accurate and reliable.
