| 目前偏光片透过率的传统测量方法依赖偏光片的相对转动，受光源偏振度以及探测器偏振响应的影响大，测量精度低。为解决上述问题，本文提出了基于Stokes矢量分析的方法，通过分析入射到偏光片以及从偏光片出射的偏振光的Stokes矢量的改变，结合最优化算法来解析样品的偏振特性，从而快速、精确地测量偏光片的透过率。该方法测量速度快、可扩展性强，对平板显示产业中光学薄膜的偏振特性的测量具有普适性。 |
| 英文摘要: |
| The traditional measurement method of the sheet polarizer transmission ratio depends on the relative rotation of the polarizers, which is greatly affected by the light source polarization degree and the detector polarization-dependent response, and has a low measurement precision. To solve the above problem, this paper proposes a method based on Stokes vector analysis, by analyzing the polarization states change between the input and output light along with optimization algorithm, to extract the polarization parameters. This method has fast measurement speed, and is universal to the characterization of polarization optical elements used in flat panel display industry. |
