【摘要】:雙波段共孔徑相機可兼顧近紅外和可見光兩者優(yōu)勢,即能保證豐富色彩信息的獲取,也可充分利用近紅外探測較好的穿霧和高靈敏度弱光探測能力。設(shè)計了工作波段為450nm~650nm和750nm~900nm的雙波段共孔徑相機,其視場角為35°×20°,F數(shù)為1.5,采用全球面復(fù)雜化雙高斯結(jié)構(gòu)。設(shè)計結(jié)果表明:MTF0.4(@50lp/mm),系統(tǒng)彌散斑10μm,畸變3%,可滿足指標(biāo)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 擄脳 20 擄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.
