本文以系统测量矩阵的行列式和条件数为目标函数，用极小化方法求出了由四分之一波片和线偏振器组成的偏振计的四个最佳旋转角。如此发现的四个角度导致偏振计对入射斯托克斯矢量的估计相对于检测到的通量的波动和构成偏振计的光学部件的角位置的误差具有最小灵敏度。提出了四个最佳角度。这四个角度也保持了测量矩阵的简单形式。
The four optimum rotation angles for a polarimeter consisting of a quarter-wave plate in conjunction with a linear polarizer are found. This is done by using the determinant and condition numbers of the system measurement matrix as objective functions in a minimization procedure. The four angles so found result in the polarimeter's estimate of the incident Stokes vector to have a minimum sensitivity with respect to fluctuations in the detected flux and errors in the angular position of the optical components constituting the polarimeter. Four optimal angles are presented. These four angles also retain a simplicity of form for the measurement matrix.
