A compressive imaging spectropolarimeter is proposed in this paper, capable of simultaneously acquiring full polarization, spatial and spectral information of the object scene. The spectral and polarization information is modulated through a combination of high-order retarders, a dispersion prism and a polarizer filter wheel. Using a random coded aperture, compressive sensing is applied to eliminate the channel crosstalk and resolution limitation of traditional channeled spectropolarimeters. The forward sensing model and inverse problem are developed. Computer simulation results are reported, followed by experimental demonstrations.
本文提出了一种压缩成像光谱偏振仪，它能够同时获取物体场景的全偏振、空间和光谱信息。光谱和偏振信息通过高阶延迟器、色散棱镜和偏振滤光轮的组合进行调制。利用随机编码孔径，应用压缩感知来消除传统通道式光谱偏振仪的通道串扰和分辨率限制。建立了前向传感模型和逆问题。报告了计算机模拟结果，随后进行了实验演示。
