【摘要】：双波段共孔径相机可兼顾近红外和可见光两者优势,即能保证丰富色彩信息的获取,也可充分利用近红外探测较好的穿雾和高灵敏度弱光探测能力。设计了工作波段为450nm~650nm和750nm~900nm的双波段共孔径相机,其视场角为35°×20°,F数为1.5,采用全球面复杂化双高斯结构。设计结果表明:MTF0.4(@50lp/mm),系统弥散斑10μm,畸变3%,可满足指标要求。
[Abstract]:The dual-band common aperture camera can take advantage of both near infrared and visible light, which can not only ensure the acquisition of rich color information, but also make full use of the good ability of near-infrared detection to penetrate fog and high sensitivity to weak light detection. A dual-band common aperture camera with a working band of 450nm~650nm and 750nm~900nm is designed, with a field of view angle of 35 掳脳 20 掳F of 1.5 and a global complex double Gao Si structure. The design results show that the system has a 10 渭 m diffuse spot and a distortion of 3 渭 m, which can meet the requirements of the index.
