Abstract Because light-field and polarization information contain much information of scenes, light-field and polarization imaging-systems can be used, e.g., for target detection, material classification, and biological analysis. However, most conventional systems rely on scanning or camera arrays, which tend to make the system both bulky and unstable. Here, we investigate a novel approach, snapshot polarimetric–volumetric imaging (SPVI), which introduces micro-polarization elements into the paradigmatic focused light-field imaging system. SPVI can simultaneously capture and reconstruct the light-field and polarization information of a scene using a single detector. The validity and accuracy of SPVI are determined via Stoke-parameter measurements and depth measurements. Compared to conventional polarimetric light-field imagers, SPVI excels with respect to compactness, robustness, and low cost. Moreover, this tool might enable new possibilities for polarimetric 3D analysis.

仅使用单个探测器的 Full-Stokes 偏振光场成像

摘要 由于光场和偏振信息包含大量的场景信息，光场和偏振成像系统可用于目标检测、材料分类和生物分析等。然而，大多数传统系统依赖于扫描或相机阵列，这往往会使系统既庞大又不稳定。在这里，我们研究了一种新方法，即快照偏振-体积成像（SPVI），它将微偏振元件引入到典型的聚焦光场成像系统中。SPVI 可以使用单个探测器同时捕获和重建场景的光场和偏振信息。SPVI 的有效性和准确性是通过斯托克参数测量和深度测量来确定的。与传统的偏振光场成像仪相比，SPVI 在紧凑性、稳健性和低成本方面表现出色。此外，该工具可能为极化 3D 分析提供新的可能性。
