宽波段折反射式航空相机设计

Wide-Band Folded-Reflective Aerial Camera

  • 摘要: 为了在15000 m平流层实现对地全天候观测,满足工作波段470~1500 nm对地分辨率达到0.1 m的要求,设计了一种长焦距折反式高分辨率CCD航空相机。通过使用H-ZK7与ZF6搭配,对长焦距和大孔径产生的二次光谱进行校正,倍率色差控满足设计要求。通过对光学系统热分析,分析出系统在不同高度下温度变化对成像质量的变化曲线。探测器采用徕卡公司M9全画幅CCD探测器,其单像元为8 μm,靶面尺寸为48 mm×36 mm;系统在100 lp/mm时达到衍射极限,满足系统成像要求。

     

    Abstract: To achieve all-weather observations in the 15000 m stratosphere and meet the ground resolution of 470–1500 nm, a long-forward charge-coupled device (CCD) aerial camera was proposed. By correcting the secondary spectra generated by the long focal length and large aperture using H-ZK 7 with ZF6, the rate color difference control meets the design requirements. The temperature curve of the system at different heights was analyzed via thermal analysis of the optical system. The detector adopted a full-frame CCD detector with a single image element of 8 μm and a target surface size of 48 mm × 36 mm; the system reached the diffraction limit at 100 lp/mm, fulfilling the imaging requirements of the system.
