We propose a geometric optimization method combined with the Coulombic energy indicator that can uniformly distribute polarization states on the Poincaré sphere. Based on this method, we investigate the optimal frames of a rotating polarizer and rotating quarter-wave plate (RPRQ)-based polarization state generator (PSG) at different numbers of modulations. We use the PSG on a dual DoFP polarimeter-based Mueller matrix microscope to measure standard samples and pathological sections for testing the performance of an optimized RPRQ. The experimental results show that this method can effectively restrain noise and improve measurement accuracy.
我们提出了一种结合库仑能量指标的几何优化方法，该方法可以在庞加莱球面上均匀分布偏振态。基于此方法，我们研究了基于旋转偏振器和旋转四分之一波片（RPRQ）的偏振态发生器（PSG）在不同调制次数下的最优框架。我们在基于双自由度偏振计的穆勒矩阵显微镜上使用该PSG来测量标准样品和病理切片，以测试优化后的RPRQ的性能。实验结果表明，该方法可以有效抑制噪声并提高测量精度。
