提出了一种采用轴对称偏振分析光学的穆勒矩阵偏振仪。轴对称光学系统具有很大的潜力，可以显示出保持在光斑内的样品的偏振特性。该方法的关键器件是一种环形束探测器。探测器的概念是拓扑和/或投影变换，并且探测器的光学配置由圆锥反射镜和/或圆锥透镜、圆柱形屏幕和CCD相机组成。利用傅里叶变换的方法，我们可以得到Mueller矩阵的性质，从没有机械和电气偏振调制的相机捕获的环形光束的强度分布。本文介绍了轴对称Mueller矩阵偏振计和环形光束探测器的工作原理及基本实验结果。
Mueller matrix polarimeter using the axisymmetrical polarized and analyzed optics is proposed. The axisymmetrical optics has a potential to bring out the polarization properties of a sample which kept in beam spot. A key device of this method is a detector named "a ring beam detector". The concept of the detector is a topology and/or a projective transformation and the optical configuration of the detector consists of a conical mirror and/or a conical lens, a cylindrical screen and a CCD camera. To use a Fourier transform method, we can get Mueller matrix properties from the intensity distribution of the ring beam captured by the camera without a mechnically and electrically polarization modulation. In this paper, principles of axisymmetrical Mueller matrix polarimeter, the ring beam detector and basically experimental results are shown.
