论文摘要
面向平面调制是一种实时极化成像的强大技术。然而，该技术遭受了线性极化过滤器和光电探测器的性能不均匀。我们研究了在存在不均匀性的情况下，研究了从区域平面调制中重建的Stokes参数。提出了两种称为最小二乘和平滑正则化方法的重建方法。通过傅立叶分析，数值模拟和实验评估所提出方法的性能。结果表明，所提出的方法可以有效地减轻由非均匀性引起的重建错误和伪像，因此可能进一步促进了面向平面技术的实际应用。
Division-of-focal-plane modulation is a powerful technique for real-time polarization imaging. This technique, however, suffers from the non-uniformity of the performance of linear polarization filters and photodetectors. We study the Stokes parameters reconstruction from the division-of-focal-plane modulation in the presence of the non-uniformity. Two reconstruction methods, named as least-squares and smoothing regularization methods, are proposed. The performance of the proposed methods are evaluated through Fourier analysis, numerical simulations, and experiments. The results indicate that the proposed methods can effectively mitigate the reconstruction errors and artifacts caused by the non-uniformity, and therefore may further facilitate the practical application of the division-of-focal-plane technique.
