摘要
介绍了一种常温红外发射率测量方法。利用双向反射分布函数测量系统，通过对物体表面双向反射分布的测量来获得其方向发射率。给出了测量原理、实验和分析。并对４种掺有隐身材料的灰、绿、草绿和黑色漆层进行了２．５～１４．５μｍ波段的方向发射率测量。
A method for measuring infrared emissivity at normal temperature is proposed.The directional emissivity is deduced from the Bidirectional Reflectance Distribution Function(BRDF)in the hemispherical scattering space of the objects.The principles,experiments and analyses are described.The directional emissivity of four kinds of paint coatings of gray,green,grass green and black color with hiddenmaterials are measured in 2.5～14.5μm wavelength.
