天然叶绿素的稳定化及伪装应用

Stabilization and camouflage application of chlorophyll

针对高光谱成像侦察威胁,分析了绿色植被可见光波段反射光谱的产生机理和模拟方法。通过分析影响天然叶绿素稳定性的各种因素,得出叶绿素的光氧化过程是阻碍其在伪装材料中得到应用的主要原因。基于叶绿素光氧化过程必须有氧参与的原理,利用高隔氧材料聚乙烯醇包封叶绿素,制备了反射光谱与菠菜一致、稳定性在3个月以上的菠菜色素/聚乙烯醇薄膜。证实了天然叶绿素在伪装材料中的应用可能性,为实现伪装材料与绿色植被的"同色同谱"提供了新途径。

According to the demand of confronting hyperspectral imaging reconnaissance, we analyzed the mech- anism and simulation technique of vegetation reflectance spectra. Based on the analysis of influencing factors of chlorophyll stability and the principle of that chlorophyll＇s photo-oxidation must have oxygen＇s participation, we prepared a spinach pigments/poly（vinyl alcohol） film, which exhibited highly similar reflectance spectra with spinach and good stability more than three months. By the fact, we confirmed the possibility of using chlo- rophyll in camouflage material, and provided a novel method to achieve the ＂concolor and conspectra＂ of camou- flage material and vegetation.
