共口徑寬光譜復(fù)眼光學(xué)系統(tǒng)設(shè)計(jì)(英文)
發(fā)布時(shí)間:2022-01-07 01:05
為了擴(kuò)大復(fù)眼光學(xué)系統(tǒng)的接收光譜,研究了一種可見光、長波紅外復(fù)眼光學(xué)系統(tǒng).推導(dǎo)了雙波段共焦面方程,建立了子眼系統(tǒng)與接收系統(tǒng)的匹配要求.子眼光學(xué)系統(tǒng)的工作波段為0.38~0.78μm和8~12μm,焦距為5mm,相對孔徑為1∶3,視場為10°.兩個(gè)波段的子眼系統(tǒng)成像位置均為2.92mm,相鄰的兩個(gè)中心光軸夾角為4.016°,共650個(gè)子眼,合并后的視場為90°.接收系統(tǒng)的焦距為4mm,視場為80°,相對孔徑為1∶3.子眼系統(tǒng)和接收系統(tǒng)的圖像質(zhì)量良好,在-40~60℃的溫度范圍內(nèi)無熱差影響.
