A method has been developed to improve the accuracy with which the polarization state of light can be characterized by the rotating quarter-wave plate technique. Through detailed analysis, verified by experiment, we determine the positions of the optic axes of the retarder and linear polarizer, and the wave plate retardance, to better than 1° for typical signal-to-noise ratios. Accurate determination of the Stokes parameters can be achieved using a single wave plate for a wide range of optical wavelengths using this technique to determine the precise retardance at each of the wavelengths of interest.
已经开发出一种方法来提高通过旋转四分之一波片技术表征光的偏振态的准确性。通过详细分析并经实验验证，我们确定了延迟器和线性偏振器的光轴位置以及波片延迟，对于典型信噪比，精度优于1°。使用该技术确定感兴趣的每个波长处的精确延迟，利用单个波片可在很宽的光波长范围内实现斯托克斯参数的精确测定。
