檢驗軍用偽裝網(wǎng)是否具有近紅外偽裝效果?

一、技術(shù)原理
1、 Technical Principles
光學(xué)檢測的一個主要目的是檢測軍事目標(biāo)表面有無葉綠素反射特征,因為軍事目標(biāo)大部分場合要適應(yīng)林地背景,而綠色植被的典型特征即是在近紅外區(qū)具有高反射(葉綠素反射)。
One of the main purposes of optical detection is to detect the presence or absence of chlorophyll reflection features on the surface of military targets, as military targets are mostly adapted to forest backgrounds, and the typical feature of green vegetation is high reflection (chlorophyll reflection) in the near-infrared region.
這一特征雖然可以通過多光譜照相或近紅外照相檢驗出來,但近紅外底片生產(chǎn)、保存、沖洗都極為不便,使這種檢測受到限制。以近紅外檢驗鏡代替上述照相檢測,使該項檢驗非常簡便。
Although this feature can be detected through multispectral photography or near-infrared photography, the production, storage, and processing of near-infrared films are extremely inconvenient, which limits this detection. Replacing the above photographic inspection with a near-infrared inspection mirror makes this inspection very simple.
自然植物綠在這種檢驗鏡下觀察呈紅橙色或紅色,人工綠色涂料則按其與植物綠色光譜反射的差異程度而呈現(xiàn)不同的顏色:光譜反射差異大的呈綠色或暗綠色,光譜反射差異微小的呈類似于植物綠顯現(xiàn)的紅橙色或紅色,光譜反射有一定差異的呈現(xiàn)出與植物綠有一定差異的紅褐色或暗褐色。

Natural plant green appears red orange or red when observed under this inspection microscope, while artificial green coatings present different colors based on the degree of difference in spectral reflectance between them and plant green: those with large spectral reflectance differences appear green or dark green, those with small spectral reflectance differences appear red orange or red similar to plant green, and those with certain spectral reflectance differences appear red brown or dark brown with certain differences from plant green.
因而檢驗時可以直觀判斷:檢驗鏡下呈綠色或暗綠色的涂料不具有近紅外隱身性能,檢驗鏡下呈現(xiàn)類似于植物紅橙色或紅色的,則是良好的防近紅外偵察隱身材料。
Therefore, during inspection, it can be intuitively judged that coatings that appear green or dark green under the inspection mirror do not have near-infrared stealth performance. Coatings that appear similar to plant red, orange, or red under the inspection mirror are good anti near-infrared reconnaissance stealth materials.
二、檢驗方法
2、 Inspection method
檢驗在室外進(jìn)行,如在室內(nèi),光照度應(yīng)在200Lux以上。頭戴檢驗鏡,將要檢驗的綠色偽裝網(wǎng)或涂料放在光照充足的地方,觀察其顏色:呈現(xiàn)紅橙色或紅色說明偽裝效果優(yōu)良;呈現(xiàn)紅褐色或暗褐色說明偽裝效果一般;呈現(xiàn)綠色或暗綠色說明沒有近紅外偽裝效果。
It is best to conduct the inspection outdoors, and if indoors, the illumination should be above 200Lux. Wearing inspection glasses, place the green camouflage net or coating to be inspected in a well lit area and observe its color: presenting red, orange or red indicates excellent camouflage effect; The appearance of reddish brown or dark brown indicates that the camouflage effect is average; The presence of green or dark green indicates that there is no near-infrared camouflage effect.
