1、 Technical Principles

光学检测的一个主要目的是检测军事目标表面有无叶绿素反射特征，因为军事目标大部分场合要适应林地背景，而绿色植被的典型特征即是在近红外区具有高反射(叶绿素反射)。

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.

这一特征虽然可以通过多光谱照相或近红外照相检验出来，但近红外底片生产、保存、冲洗都极为不便，使这种检测受到限制。以近红外检验镜代替上述照相检测，使该项检验非常简便。

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.

自然植物绿在这种检验镜下观察呈红橙色或红色，人工绿色涂料则按其与植物绿色光谱反射的差异程度而呈现不同的颜色：光谱反射差异大的呈绿色或暗绿色，光谱反射差异微小的呈类似于植物绿显现的红橙色或红色，光谱反射有一定差异的呈现出与植物绿有一定差异的红褐色或暗褐色。

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.

因而检验时可以直观判断：检验镜下呈绿色或暗绿色的涂料不具有近红外隐身性能，检验镜下呈现类似于植物红橙色或红色的，则是良好的防近红外侦察隐身材料。

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、检验方法

2、 Inspection method

检验在室外进行，如在室内，光照度应在200Lux以上。头戴检验镜，将要检验的绿色伪装网或涂料放在光照充足的地方，观察其颜色：呈现红橙色或红色说明伪装效果优良；呈现红褐色或暗褐色说明伪装效果一般；呈现绿色或暗绿色说明没有近红外伪装效果。

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.
