【摘要】：光谱和偏振辐射特性是实现精细目标识别的重要光学参量,融合光谱和偏振信息分量的光谱偏振成像探测技术有效利用两者的互补性,提高在复杂背景环境下的目标识别能力,在环境监测、军事侦察和大气分析等领域具有巨大的发展潜力。围绕目标的光谱和偏振信息探测问题,研究了一种基于微偏振阵列的干涉型高光谱偏振成像技术。在研究Sagnac干涉型高光谱成像技术的基础上,利用微偏振阵列调制原理引入Stokes偏振分量信息探测。通过分析系统的工作原理,设计了系统的干涉成像光路模型,并对光谱信息反演方法以及偏振信息提取方法进行了讨论分析。搭建了实验装置,对实际场景目标进行了光谱偏振成像实验,得到了较好的实验结果。研究表明:该光谱偏振成像技术不仅具有高光通量、高光谱分辨率的优点,而且能够实现偏振信息的同步获取。
[Abstract]:Spectral and polarization radiation characteristics are important optical parameters to realize fine target recognition. Spectral polarization imaging detection technology which combines spectrum and polarization information components can effectively utilize the complementarity of the two to improve the ability of target recognition in complex background environment.It has great potential in environmental monitoring, military reconnaissance and atmospheric analysis.An interferometric hyperpolarization imaging technique based on micro-polarization array is proposed to detect the spectral and polarization information of the target.Based on the study of Sagnac interferometric hyperspectral imaging technology, Stokes polarization component information detection is introduced by using the principle of micro-polarization array modulation.By analyzing the working principle of the system, the optical path model of the system is designed, and the methods of spectral information inversion and polarization information extraction are discussed and analyzed.The experimental device is built, and the spectral polarization imaging experiment of the actual scene target is carried out, and good experimental results are obtained.The results show that the spectral polarization imaging technique not only has the advantages of high luminous flux and high spectral resolution, but also can obtain the polarization information synchronously.
