摘要
设计了一种利用K9玻璃材料制成的空间转向反射棱镜,其具有相对旋转90°的两个反射面,光束经两个反射面反射时入射角相等,光束反射时产生的相位差大小相等,但方向相反,可以互相抵消,确保了反射光和入射光偏振特性一致,实现偏振特性的自补偿。通过测试实验并经Matlab拟合,验证了该空间转向反射棱镜具有很好的偏振自补偿特性。
Using single reflecting prism and aluminium coated mirror as a component which realizes spacial veer transmission of polarization light, there is a phasic difference that would lead to the polarization variety of reflecting light compared with incidence light between S-wave and P-wave. Applying single reflecting prism and aluminium coated mirror to synthetical LCD parameters testing system, it will create system error. To reduce system error and improve measuring precision, a spacial veer reflecting prism made of K9 glass is designed. The spacial veer reflecting prism has two relatively revolving 90 ° reflecting planes and the same incident angle. Using such prism as veer transmission component, the phasic difference aroused by one reflecting plane is equal to that by the other, but the direction is reverse. The polarization character of reflecting light and incident light can be accordant because the two phasic differences will be counteracted. It is proved that spacial veer reflecting prism can automatically compensate polarization character very well by our experiment and Matlab software.
