可見(jiàn)光偽裝主要通過(guò)模仿背景環(huán)境的反射光譜，減少目標(biāo)與背景的反射光譜差異，從而降低目標(biāo)的可探測(cè)性。目前可見(jiàn)光偽裝主要依靠迷彩涂層實(shí)現(xiàn)。所謂迷彩，就是軍事上使用的可能使人產(chǎn)生錯(cuò)覺(jué)的色彩。迷彩圖案可以使士兵與背景環(huán)境相融合，提高士兵的作戰(zhàn)能力和行動(dòng)的隱蔽性。

Visible light camouflage mainly imitates the reflection spectrum of the background environment to reduce the difference in reflection spectra between the target and the background, thereby reducing the detectability of the target. At present, visible light camouflage mainly relies on camouflage coatings. The so-called camouflage refers to the colors that may create illusions in military use. Camouflage patterns can blend soldiers with the background environment, enhancing their combat capabilities and the concealment of their actions.

迷彩主要可以分成 3 種：保護(hù)迷彩、變形迷彩和仿造迷彩。保護(hù)迷彩只有單一色調(diào)，如綠色，工藝簡(jiǎn)單，生產(chǎn)成本低，但是偽裝效果差；變形迷彩由多種形狀不規(guī)則、大小不一的斑點(diǎn)組成，主要用于活動(dòng)目標(biāo)；仿造迷彩是模仿自然背景圖案和顏色的迷彩，多用于固定目標(biāo)。

Camouflage can be mainly divided into three types: protective camouflage, deformation camouflage, and imitation camouflage. Protective camouflage only has a single color tone, such as green, with simple craftsmanship and low production costs, but the camouflage effect is poor; Deformable camouflage is composed of various irregularly shaped and varying sized spots, mainly used for moving targets; Imitation camouflage is a camouflage that imitates natural background patterns and colors, often used to fix targets.

保護(hù)迷彩和變形迷彩屬于比較普通的迷彩。隨著偵查設(shè)備的不斷發(fā)展，設(shè)備的分辨率很大程度上得到提高，普通的迷彩已經(jīng)不能滿(mǎn)足要求，所以數(shù)碼迷彩應(yīng)運(yùn)而生。在某種意義上數(shù)碼迷彩也屬于仿造迷彩。所謂數(shù)碼迷彩就是由一個(gè)個(gè)稱(chēng)之為“像素”的小方格構(gòu)成的迷彩圖案。早在20世紀(jì)70年代末，美國(guó)就對(duì)數(shù)碼迷彩進(jìn)行了研究，但研究效果不理想。到90年代，數(shù)碼迷彩技術(shù)快速發(fā)展，尤其是加拿大研制出的數(shù)碼迷彩林地偽裝服，具有良好的可見(jiàn)光偽裝性能。數(shù)碼迷彩通過(guò)色塊的多種組合，使得不同顏色間的邊緣模糊和破碎，且顏色對(duì)比度很弱。相比之下，普通迷彩斑點(diǎn)之間的界線(xiàn)分明，邊緣平滑，色塊顏色對(duì)比程度高。因此，數(shù)碼迷彩更加容易使士兵與背景環(huán)境相融合，并且方便對(duì)圖案的尺寸大小進(jìn)行精普通迷彩 數(shù)碼迷彩

Protective camouflage and deformation camouflage are relatively common camouflage. With the continuous development of reconnaissance equipment, the resolution of the equipment has been greatly improved, and ordinary camouflage can no longer meet the requirements, so digital camouflage has emerged. In a sense, digital camouflage also belongs to imitation camouflage. The so-called digital camouflage is a camouflage pattern composed of small squares called "pixels". As early as the late 1970s, the United States conducted research on digital camouflage, but the research results were not satisfactory. By the 1990s, digital camouflage technology had rapidly developed, especially the digital camouflage forest camouflage suit developed by Canada, which had excellent visible light camouflage performance. Digital camouflage uses various combinations of color blocks to blur and break the edges between different colors, with weak color contrast. In contrast, the boundaries between ordinary camouflage spots are clear, the edges are smooth, and the color contrast of the blocks is high. Therefore, digital camouflage makes it easier for soldiers to blend in with the background environment and facilitates precise sizing of patterns
