摘要
为获得目标和场景的偏振信息,提高目标识别和地物探测的准确度,设计了基于液晶相位可变延迟器(LCVR)和声光可调滤波器(AOTF)的高光谱偏振成像探测系统。首先介绍了偏振成像探测的原理,然后给出了探测系统的结构,并对其光学系统的各元件进行了合理的参数分配,最后利用编制的信息处理软件对系统采集的高光谱偏振图像进行了处理,处理结果能够反映出目标的光谱特性和偏振特性,对于复杂背景下的目标探测与识别具有重要的应用价值。
In order to acquire polarization information of target and background, hyperspectral polarization image system based on Liquid Crystal Variable Retarders （LCVR） and Acousto-optic Tunable Filter （AOTF） was designed to improve the accuracy of detection of target and background. Firstly, the principle of polarization detection and the work principle of AOTF were described. And then the structure of the system was given. In the mean while, the parameter of optic component was distributed reasonably. Finally, the hyperspectral polarization images captured by the system were analyzed through the polarization information process software programmed by MATLAB. The calculated results show that the polarimetric and spectral characteristics of target are obvious. The system is of significance for object detection and recognition.
