高分辨率单光子成像实验数据集（2020年）

项目团队针对远距离成像中视场随成像距离增加逐渐发散导致分辨率逐渐降低的问题，提出了基于亚像素精细扫描的高分辨单光子成像方法。配合成像样机的精细扫描设置，团队在8.2km的尺度下完成了该方案的原理性验证，对8.2km外的人形目标的各类姿势实现了有效的重构，横向分辨率可达5cm，实现了约3.3倍的系统分辨率的提升。本数据集为人形目标的系列成像结果。A research team addressed the issue of gradually degraded resolution in long-distance imaging, which stems from the expanding field of view (FOV) as the imaging distance increases. To mitigate this problem, the team proposed a high-resolution single-photon imaging method based on sub-pixel precision scanning. Using the precision scanning setup of the developed imaging prototype, the team carried out a proof-of-principle validation of this scheme at a distance of 8.2 km. The method successfully reconstructed various postures of human-shaped targets at 8.2 km, achieving a lateral resolution of up to 5 cm and an approximately 3.3-fold enhancement in the system's resolution. This dataset contains a series of imaging results for human-shaped targets.
