【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.更多还原

【Abstract】 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.更多还原
