	材料的可见光光谱特性,可以应用于土壤水分的估测,植物的叶绿素含量预测、蛋白质含量的预测、数字喷墨印刷图像的呈色控制、目标隐身与反隐身等多个领域。 利用 ATP9100 地物光谱辐射计设计了目标材料反射率谱测量实验,实验内容包括:反射率谱的测试、定标、不确定度评估。 实验设计了两组实验:(1)不同颜色材料的光谱反射率测试;(2)相同颜色不同反射率谱材料测试。 实验(1)主要培养学生光谱反射率测试基本操作、不确定度分析以及不同颜色的光谱反射率分析能力;实验(2)主要是验证不同材料的“同色异谱”现象,从中引出可见光隐身与反隐身的发展,将最新的科研成果融入教学中。

															Abstract:  
	Using the ATp9100 ground object spectral radiometer to measure typical materials , obtain theispectral rellectance images , and perform uncertainty calculations and comparative analysis,The average relativeuneertainty of various materials is caeulated to be below 6%; The phenomenon of “ homochromaticmetamerism” was verified through test data, and the results showed that objects with the same color. Theispectral rellectance may also vary.lt leads to the latest progress and development trend of hyperspectral stealthteehnology,integrating scientifie research content into teaching work.
