摘要:
为了实现快速提取目标在不同光谱下偏振辐射特性的目的,设计了一款可见光为0.38~0.76 μm,近红外为0.85~1.6 μm双波段目标探测识别的分孔径同时偏振成像系统,该系统由四个分孔径子系统组成和一个公共镜头组组成。设计结果表明:该系统对可见光和近红外波段分别进行偏振编码成像时,可见光波段和近红外波段可以同时获得不同光谱的偏振图像信息,保证了各个光谱对同一目标成像的一致性,实现了对同一目标不同辐射特性偏振图像的采集。当光学系统的焦距为60 mm,F数为5,视场角2ω为3.8°,系统反应速度快,整体成像质量良好,可实现昼夜全天候工作。
Abstract:
In order to quickly detect useful information and improve the ability to detect and recognize targets in the complex radiation environment,a sub-aperture polarization imaging system with dual-band target detection and recognition of visible light of 0.38~0.76 μm and near-infrared of 0.85~1.6 μm is designed.The system consists of four sub-apertures and a common lens array.The results show that polarization images can be obtained directly without changing the optical path,and the system produces polarization imaging with different bands,ensuring consistency of information of different band target,and realizing the acquisition of the polarization images of different radiation characteristics of the same target.When the focal length of the optical system is 60 mm,F number is 5,and the field of view angle 2ω is 3.8°,the system has fast response and good overall image,and can work day and night in all weathers.
