单光子成像系统距离分辨率标定数据集（2021年）

项目团队研制了适用于百公里量级的远距离单光子成像样机，并基于该样机在新疆乌鲁木齐开展了系列外场实验。其中，为标定对该系统的距离分辨率，团队在距离成像样机113.6km处放置了一个角反镜，利用样机对该反射镜的探测结果实现该标定过程。本数据为成像样机接收到的113.6km外反射镜的回波信号，该数据的时间展宽约为1ns，说明成像样机具备约15cm的距离分辨率。

A research team developed a long-range single-photon imaging prototype capable of hundred-kilometer scale ranging, and conducted a series of field experiments in Urumqi, Xinjiang Uygur Autonomous Region using this prototype. Specifically, to calibrate the range resolution of the system, the team placed a corner cube retroreflector at a distance of 113.6 km from the imaging prototype, and completed the calibration procedure using the detection results of the prototype against this retroreflector. This dataset contains the echo signals received by the imaging prototype from the retroreflector situated 113.6 km away. The temporal broadening of this dataset is approximately 1 ns, which demonstrates that the imaging prototype has a range resolution of about 15 cm.
