摘要/Abstract

摘要：

物质材料例如涂层、金属、电介质等有其各自的偏振特性。Stokes参量或是Mueller矩阵表示了偏振量化信息与材料性质的关系。介绍了Mueller矩阵测量方法，使用He-Ne（入=632.8 nm）激光器经过起偏器产生的偏振光照射在铝样品上，并经偏振分析光学系统，获取样品Mueller矩阵元素测量图像数据。在给出延迟器校正结果的前提下，使用64个偏振测量图像，并采用最小二乘法减小误差，给出了铝板样品的偏振反射Mueller矩阵，比较分析了水平/垂直、 / 和左旋/右旋圆偏振分量随样品转角变化时的退偏特性曲线。结果表明，铝板的圆偏光与线偏光的退偏度显著，为使用圆偏振实现探测提供可能性。

Abstract:

The polarization characteristics of light scattered by several materials such as paint, metal, dielectric layers is significant. The stokes-Mueller formalism is used to study the depolarizing properties of sample. The Mueller matrix measurement is introduced. The polarized light from a He-Ne laser（入=632.8 nm ）is used, which is generated by a polarization generator, and focuses onto the surface of the aluminium sample, then passes through the polarization-analysis optics onto a CCD camera, at last the Mueller matrix element image data is obtained. The retardation plates are submitted to a calibration procedure, 64 images are digitized and a generalized linear least square fit is calculated. The horizontal or vertical polarization, linear 45- or 135-polarization, and right or left circular polarization are compared and analyzed. The results show that for alumiunum plate, circular states have greater depolarization than linear states.
