Research towards practical applications of ghost imaging lidar system especially in longer sensing distance has been urgent in recent years. In this paper we develop a ghost imaging lidar system to boost an extension of remote imaging, where the transmission distance of the collimated pseudo-thermal beam can be improved hugely over long range and just shifting the adjustable lens assembly generates wide field of view suiting for short-range imaging. Based on the proposed lidar system, the changing tendency of illuminating field of view, energy density, and reconstructed images is analyzed and verified experimentally. Some considerations on the improvement of this lidar system are also discussed.
近年来，对鬼成像激光雷达系统在实际应用中的研究，特别是在更远的探测距离方面，已经非常迫切。在本文中，我们开发了一种鬼成像激光雷达系统，以实现远程成像的扩展，其中准热光束的传输距离可以在长距离上得到极大地提高，只需移动可调透镜组件即可产生适合短距离成像的宽视场。基于所提出的激光雷达系统，分析和实验验证了照明视场、能量密度和重建图像的变化趋势。还讨论了对该激光雷达系统进行改进的一些考虑因素。
