An imaging variable retardance polarimeter was developed and tested by Tyo and Turner [Proc. SPIE 3753, 214 (1999)]. The signal-to-noise ratio (SNR) in the reconstructed polarization images obtained with this system varied for the four Stokes parameters. The difference in SNR is determined to be due to differences in the Euclidean lengths of the rows of the synthesis matrix used to reconstruct the Stokes parameters from the measured intensity data. I equalize (and minimize) the lengths of the rows of this matrix by minimizing the condition number of the synthesis matrix, thereby maximizing the relative importance of each of the polarimeter measurements. The performance of the optimized system is demonstrated with simulated data, and the SNR is shown to increase from a worst case of -3.1 dB for the original settings to a worst case of +5.0 dB for the optimized system.
Tyo和Turner开发并测试了一种成像可变延迟偏振计[《国际光学工程学会会刊》3753卷，214页（1999年）]。使用该系统获得的重建偏振图像中的信噪比（SNR）因四个斯托克斯参数而异。信噪比的差异被确定是由于用于从测量强度数据重建斯托克斯参数的合成矩阵各行的欧几里得长度不同。我通过最小化合成矩阵的条件数来均衡（并最小化）该矩阵各行的长度，从而最大化每个偏振计测量值的相对重要性。用模拟数据展示了优化系统的性能，并且信噪比显示从原始设置的最坏情况-3.1 dB增加到优化系统的最坏情况+5.0 dB。
