Abstract: 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.
