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.

摘要

我们展示了一种基于压缩采样和单光子计数的全斯托克斯偏振成像系统。专门开发了基于现场可编程门阵列的控制和同步计数模块，以控制用于不同方向偏振成像的旋转台。此外，它可以在每次测量时将二进制随机矩阵加载到数字微镜器件控制器中，并同时对从光子计数光电倍增管输出的单光子脉冲进行计数。该系统可以实现目标在不同偏振方向下的高灵敏度单光子压缩成像。在此基础上，可以获得高质量的斯托克斯参数图像和线偏振图像的角度。实验结果表明，在非常低的采样率下即可重建偏振信息。
