Paper Abstract

Birefringence is an important optical parameter of anisotropic crystal, which is determined by multi factors, such as component structure growth condition and wavelength. There are many methods to measure birefringence, but they usually applicable for single wavelength and birefringence is obtained by primary refractive index, precision generally is 10-4 . The accurate method is electro-optic modulation and interference,for which the spectral range is not only visible region, but also ultraviolet and infrared according to needs. Birefringence precision of 10-5 can obtain without complex data processing. The construction is simple and technical index is easy to control.
