【摘要】：為滿足數(shù)字超高速成像需求,提高相機(jī)的時(shí)間分辨率,設(shè)計(jì)了一種工作于350nm~800nm寬波段的八分幅相機(jī)光學(xué)系統(tǒng)。該系統(tǒng)采用光闌外置的會(huì)聚光分光結(jié)構(gòu),可同時(shí)獲得同一物面的八幅相同圖像,針對(duì)光學(xué)系統(tǒng)后截距、像方數(shù)值孔徑等重要光學(xué)參數(shù)對(duì)像面照度差的影響、寬光譜成像的色差校正等問(wèn)題進(jìn)行了分析。在Code V中對(duì)中繼鏡頭進(jìn)行設(shè)計(jì)優(yōu)化,像面大小可達(dá)26mm,像方MTF在40lp/mm時(shí)對(duì)比度達(dá)0.5以上,畸變小于1%,分幅后系統(tǒng)像面照度差在±10%以?xún)?nèi)。模擬結(jié)果表明:八分幅相機(jī)光學(xué)系統(tǒng)各幅圖像一致性較高。
[Abstract]:In order to meet the requirement of digital ultra-high speed imaging and improve the time resolution of the camera, an octave camera optical system working in the wide band of 350nm~800nm is designed. In this system, eight same images of the same object surface can be obtained simultaneously by using the condensed light splitting structure outside the aperture. The influence of the important optical parameters such as the back intercept of the optical system and the numerical aperture of the image on the illumination difference of the image plane can be obtained at the same time. The color difference correction of wide spectrum imaging is analyzed. The design of relay lens in Code V is optimized, the image plane size can reach 26mm, the contrast of image square MTF is more than 0.5 at 40lp/mm, the distortion is less than 1, and the illumination difference of image plane is less than 鹵10%. The simulation results show that the image consistency of the optical system of the octave camera is high.
