摘要
利用双折射晶体的反射和折射特性提出四种两元复合式平行分束偏光棱镜设计,其特点是分束距大,消光比和透射比高,分离角小,非常适宜于大间隔光束调制和光开关系统,以冰州石晶体为例给出了各器件的工作参数。
Four types of parallel beam-splitting polarizer are provided using a birefringent crystal. The features of the devices are large displacement, high extinction ratio, high transmittance and small splitting angle. They are expecially designed for the usage of optical switch and modulating systems, and with calcite as an example, the properties of several differet designs are compared.
