摘要
描述了图谱合一的新型三维超光谱侦察技术,并基于凹面光栅和背照减薄CCD技术,构建了一种UV/VIS/NIR宽波段超光谱系统.在对视场、弥散斑、探测器像素间隔、F数等几何光学参数以及光谱带宽、工作波段、光谱分辨力等物理参数多重权衡设计的基础上,完成了对给定系统的光学参数设计.对建立的系统进行了测试和应用,实验评价获得了分辨力测试图像的空间弥散斑小于2个像素,对隐蔽物体的探测具有明显效能,为战场侦察和反伪装识别提供了技术途径.
A hyperspectral reconnaissance system combining image with spectrum is discussed, based on concave grating and BTCCD, an UV/VIS/NIR broadband hyperspectral system (HIS) is constructed. After tradeoff among the geometrical optical parameters(FOV,blur spot, pixel pitch, F etc. )and physical optical parameters(bandwidth, waveband, spectral resolution etc). Optical design for the given system is discussed. From tests and experiments, an image having a blur spot less than 2pixel is obtained and the capability of detecting a camouflage object is verified at last, providing a new way in battlefield reconnaissance and auto target recognition.
