摘要:
讨论一种新型激光雷达成像方法,建立以皮秒条纹管相机为接收器的激光雷达成像系统.该系统采用皮秒钇铝石榴石(yttrium aluminium garnet,YAG)激光器作为激光源,通过可调延时器和标准具对条纹管相机的扫描速度和非线性进行标定.结果表明,该系统中皮秒条纹管相机的时间分辨率优于2 ps,非线性小于2%,具有时间分辨率高、测量时间短和光谱测量范围宽等特点.用该系统对不同距离两物体进行成像实验,理论计算出两物体的距离差与实际距离差较接近,从而验证了采用该系统进行激光雷达成像的可行性.为基于皮秒扫描相机的激光雷达成像系统的建立提供了理论与实验依据.
Abstract:
A new type imaging laser radar system based on picosecond streak tube camera was discussed. The picosecond streak tube camera and the picosecond YAG LASER were used as receiver and lamphouse respectively. The parameters of picosecond streak tube camera,i.e.,sweep speed and nonlinearity were calibrated by tunable delay generator and a set of etalons. Experimental results show that the temporal resolution of this system is less than 2 ps,and the nonlinearity of this system is less than 2%. The system has high temporal resolution, short measurement time and wide range of spectral characteristics of measurement.The minor error between the calculated distance and the actual distance has demonstrated that this proposed imaging method is feasible and provides a theoretical and experimental reference for the new type of imaging laser rader.
