Full Stokes single photon compressive polarization imaging

Abstract

We demonstrate a full Stokes polarization imaging system based on compressed sampling and single photon counting. The control and synchronization counting module based on field-programmable gate array is specially developed to control the rotation stage for polarization imaging at different directions. Additionally, it can load the binary random matrix into a digital micro-mirror device controller for each measurement and count the single photon pulse output from the photon counting photomultiplier tube simultaneously. The system can realize high-sensitivity single photon compressive imaging of the target under different polarization directions. On this basis, the high-quality Stokes parameter images and the angle of the linear polarization image can be obtained. The experimental results show that the polarization information can be reconstructed at a very low sampling ratio.
