In this paper, we present the first in-depth analysis of the bandwidth tradeoffs, error performance, and noise resiliency of full-Stokes micropolarizer array (MPA) designs. By applying our Fourier domain tools that provide a systematic way for arranging information carriers and allocating bandwidth, we develop a number of new full-Stokes MPA layouts and compare them to the existing full-Stokes MPAs in the literature, all of which use 2×2 pixel unit cells to build the MPA. We compare the reconstruction accuracy afforded by these traditional designs with the generalized 2×L family of MPAs, a 3×3 tiling, as well as a 2×2×3 layout that uses multiple snapshots and trades off temporal resolution for spatial resolution. Of those systems, the hybrid spatiotemporally modulated 2×2×3 MPA provisions the most bandwidth and provides the highest reconstruction accuracy, while the modified 2×L family remains the best performing single-snapshot MPA. Additionally, we study the degradation of reconstruction accuracy under the presence of systematic error in MPA fabrication. We find that reducing the amount of correlated error is by far the largest factor in ensuring robust performance.
在本文中，我们首次对全斯托克斯微偏振器阵列（MPA）设计的带宽权衡、误差性能和噪声弹性进行了深入分析。通过应用我们的傅里叶域工具，该工具为排列信息载体和分配带宽提供了一种系统方法，我们开发了一些新的全斯托克斯MPA布局，并将它们与文献中现有的全斯托克斯MPA进行比较，所有这些MPA均使用2×2像素单元来构建MPA。我们将这些传统设计提供的重建精度与广义2×L系列MPA、3×3平铺以及使用多个快照并以时间分辨率换取空间分辨率的2×2×3布局进行了比较。在这些系统中，混合时空调制的2×2×3 MPA提供了最多的带宽并提供了最高的重建精度，而改进的2×L系列仍然是性能最佳的单快照MPA。此外，我们研究了MPA制造中存在系统误差时重建精度的下降情况。我们发现，减少相关误差量是确保稳健性能的最大因素。
