Non-scanning 3-D range-gated imaging lidar can improve the detection capability, image quality and distance accuracy of the system by suppressing back scattering and removing fuzzy distance. The non-scanning 3-D range-gated imaging lidar system composed of commercial products is introduced, and the experimental system is tested. Results show that the system range resolution is 1.5 m at 40 m range indoor, and target shape and distance information can be acquired accurately. The system range resolution decreases to 3 m at 960 m range outdoor, however, target can still be identified. Finally, the system's shortcomings are pointed out.
