3、面的試驗(yàn)應(yīng)用,闡述了偏振成像在靶場應(yīng)用的前景和優(yōu)勢(shì),提出了一種基于偏振成像的光學(xué)成像系統(tǒng),并對(duì)現(xiàn)有設(shè)備提出了偏振化改造方案。通過利用目標(biāo)、環(huán)境的偏振特性,利用強(qiáng)度+偏振的組合模式,可提升現(xiàn)有設(shè)備的目標(biāo)探測和成像識(shí)別能力。最后,對(duì)偏振技術(shù)應(yīng)用和發(fā)展進(jìn)行了展望。關(guān)鍵詞:偏振成像;Stokes量;偏振度;光學(xué)背景;空間目標(biāo)中圖分類號(hào):V556.5;0436.3文獻(xiàn)標(biāo)志碼:A文章編號(hào):1674—5620(2016)04—0264—06DOI:10.7642/j.issn.1674—5620.2016-04-
