单狭缝条纹管激光雷达四维成像实验

Experiment of Four-Dimensional Imaging with Single-Slit Streak Tube Lidar

提出了一套用于远距离目标成像的实验设备,介绍了单狭缝条纹管激光成像雷达(STIL)四维(4D)成像实验平台的实验过程。利用这套设备得到了702 m目标条纹像,解释了条纹像和目标之间的对应关系,用多幅条纹像重构了目标的四维图像。简要分析了狭缝、束散角等参数对成像精度的影响。实现了单狭缝条纹管激光成像雷达对远距离目标的成像,且距离分辨率可以达到0.5 m。

A streak tube imaging lidar（STIL） system is established to finish a field imaging experiment.With thirty streak images piled up,reconstruction contrast map and range map of a target 702 m away are presented.Relationship between streak images and target detail is marked.The range resolution is better than 0.5 m in the experimental result.Imaging precision affected by streak and divergence of laser beam is discussed.
