圆偏振滤光镜反向使用时的摄影性能

The Photographic Performance of a Circular Polarizing Filter Used Inversely

根据偏振光干涉的原理 ,分析了摄影中反向使用圆偏振滤光镜时出射光随入射光及圆偏振镜旋转方位的变化情况。将圆偏振镜与线偏振镜组合 ,并使 1 4波片位于线偏振镜之间 ,测定出线偏振镜和圆偏振镜相对旋转至不同方位时的分光透过率曲线 ,探讨了入射光为线偏振光时出射光因偏振光的干涉而相应出现的强度和色度变化 ,并以此为模型 ,对圆偏振镜反向使用时的摄影性能进行研究和总结。

The paper analyzes the change of the exit light from a circular polarizing filter used inversely according to the interference theory of polarized light, measures the spectral transmittance curves with the combining of circular polarizing filter and linar polarizing filter, and summarizes the photographic performance of the circular polarizing filter used inversely.
