We proposed a method for polarization ghost imaging based on single photon counting. With the time-correlated single-photon-counting technique, we can construct photon time distribution histograms and select a distance gate to accurately estimate the light intensity. Experiments are performed to realize discrimination of the object from the background of different materials in weak illumination. In the situation that ambient noise is significantly stronger than the signal, our method still can retrieve an image as ambient noise is mostly filtered out through distance gate selection. We suppose that our method may facilitate applications in remote target discrimination and biological imaging.
我们提出了一种基于单光子计数的偏振鬼成像方法。利用时间相关单光子计数技术，我们可以构建光子时间分布直方图并选择距离门来准确估计光强。进行实验以实现在弱光照下从不同材料的背景中区分物体。在环境噪声明显强于信号的情况下，由于通过距离门选择大多滤除了环境噪声，我们的方法仍然可以检索到图像。我们认为我们的方法可能有助于远程目标识别和生物成像应用。
