Abstract

In this Letter, we investigate a snapshot spectral-polarimetric-volumetric imaging (SSPVI) system using a single detector. Through compressed acquisition and reconstruction, SSPVI can achieve spectral imaging ${(x,y,\lambda)}$, polarization imaging ${(x,y,\psi ,\chi)}$, and light field imaging ${(x,y,\theta ,\varphi)}$ simultaneously. The newly discovered performance is showcased by attaining the spectral-polarimetric-volumetric video and different laboratory accuracy experiments. These never-seen-before capacities of the camera open new prospects for many applications, such as biological analysis, object recognition, and remote sensing.

NameDescription
Supplement 1       The supplement.
Visualization 1       To highlight SSPVI’s snapshot multi-dimensional-imaging capability, we visualized a dynamic scene consisting of two white boards with black letters, one artificial leaf, one true leaf and one linear polarizer.
Visualization 2       To evaluate the polarimetric imaging performance of the SSPVI system, we visualized a dynamic scene consisting of a glass window, which rotates with a period of 2s, and there are four linear polarizers on its periphery.
