为了提高多狭缝条纹管的成像性能,利用改进的光锥和多狭缝条纹管搭建了一套激光成像雷达实验系统。光锥的光纤排布方式由前端的12832转变为后端的8512,从而将平面像转变为8行线状条纹像,实现了探测器对视场的有效探测。系统的激光波长为532 nm,成像像元数为12832,空间分辨率<0.3 mrad,可进行全天候工作。利用该装置完成了外场建筑物目标成像实验,分别获得了1.7 km目标的无扫描成像结果以及720 m目标的扫描成像结果。实验结果表明,所研制的激光成像雷达能够获得远距离目标的激光图像,强度像可较好地展现建筑物目标的各区域,轮廓清晰;距离像可有效地区分不同距离的区域,距离分辨能力较好。
In order to effectively improve the imaging property of multiple-slit streak tube
an experimental platform for Multiple-Slit Streak Tube Laser Imaging Lidar(MS-STIL) was established with a domestically-made optical taper and streak tube. The fiber arrangements of the optical taper were converted from 12832 at fore-end to 8512 at back-end
thus changing the planar image to 8 stripes image and enabling the detector to achieve effective detection of field of view. The laser wavelength of this system is 532 nm
with an imaging pixel element of 12832 and a spatial resolution lower than 0.3 mrad
and all-weather operations can be achieved. On the platform
imaging experiments for out-field building targets were performed
from which the non-scanning image of 1.7 km target and the scanning image of 720 m target were obtained respectively. The imaging results indicated that the proposed MS-STIL can capture the laser images of long-distance targets
as the intensity image can well display the areas where the building target is located
with clear outline; the distance image can effectively divide the areas with different distances
with relatively high distance resolution.
