摘要
条纹管激光成像雷达(STIL)是近10年发展起来的一种新型闪光式激光成像雷达,以瞬态光学器件条纹管作为探测接收器,可做到大视场、高分辨,分单狭缝和多狭缝两种体制。由于条纹管不能直接输出四维像(三维(3D)距离像加一维(1D)强度像),针对两种体制的条纹图像,使用峰值探测法对远距离目标条纹像进行重构,获得完整的条纹管激光成像雷达四维像。实验结果表明,条纹管激光成像雷达是一种高分辨、高帧频的成像器件,具有较好的应用前景。
Streak tube imaging lidar （STIL） is a new type of flash laser radar, and its receiving detector is the transient optical streak tube. The characteristic of STIL is of wide field of view and high resolution. It has two types, single slit and multiple slits. Because the streak tube can not directly output the four-dimensional image （threedimensional （3D） range image and one-dimensional （1D） intensity image）, for the streak images of the two types, peak-detection algorithm is used to reconstruct the far-distance target in this paper. And the complete fourdimensional images of STIL are obtained. The experiment results show that STIL is an imaging device of high resolution and high frame frequency, so it will have promising application.
