90°分束偏光镜视场角内的分束角和光强分束比

The Splitting Angle and Light Intensity Splitting Ratio of 90° Polarization Splitting Prism within its Viewing Field Angle

从理论上分析了非偏振光经过了90°分束偏光镜后,在视场角内,o、e光的光强分束比和分束角随入射角变化的关系,并进行了实验验证。结果表明:在误差所允许的范围内,实验所测的光强分束比和分束角随入射角的变化与理论计算是一致的。

The relation of o,e splitting angle and light intensity splitting ratio within its viewing field angle after nonpolarized light through the 90° polarization splitting prism was given theoretically,and they are changeable with incident angle.The tested result is well in agreement with calculation value.
