利用光纤分束器和一个单光子探测器,提出了一种微弱光探测下的单脉冲光子计数方案。将该光子计数方案与关联成像原理结合,搭建了一套光子计数探测模式下的关联成像实验平台。实验研究了微弱光探测条件下光子计数的动态范围对关联成像质量的影响,分析并探讨了基于光子计数的关联成像需进一步深入研究的问题。
By utilizing a fiber beam splitter and N single-photon sensors, a method for single pulse photon counting in the case of weak light signal detection is proposed. Combining the photon counting method and ghost imaging, a ghost imaging platform based on photon counting is established. The effect of dynamic range of the photon counting on the ghost imaging is investigated by experiments, and some problems to be further studied about this method are also discussed.
