Design and development of a new high spectral coating

在400~2 500nm波段内系统分析了绿色植物的光谱曲线特征以及产生机理。在此基础上,采用BaCl_2·2H_2O、ZnSO_4·7H_2O和铬绿作为基本填料,聚脲作为树脂基体制备涂层,试验结果表明,所得涂层在400~2 500nm波段内具有和绿色植物相似的光谱曲线,经与桑叶的光谱曲线对比,相关系数达到了0.9249,相似角余弦值达到了0.9883,且整体曲线符合深绿涂层的光谱通道要求。并对涂层进行了高温下的光谱稳定性测试,结果表明涂层在高温下的光谱稳定性良好。涂层能够有效地对抗高光谱探测技术的威胁。

The characteristics and mechanism of the spectral curves of green plants were analyzed in the 400-2 500 nm band.On this basis,BaCl2·2H2O、ZnSO4·7H2O and chrome green were used as the basic filler and polyuria was used as a resin matrix to prepare a coating.Test results showed that the coating had a similar spectral curve with green plants in the range of 400-2 500 nm.When compared the spectrum curve with that of mulberry leaves,the correlation coefficient reached 0.9249,the cosine of the similar angle reached 0.9883,and the whole curve fitted the spectral channel green coating requirements.The spectral stability of the coating was tested at high temperature.The results showed that the spectral stability of the coating was good at high temperature.The coating could effectively combat the threat of hyperspectral detection technology.
