【摘要】 论述了空间姿态敏感器表面材料测量的基本原理,即光谱漫反射基本原理和光谱相对空间反射分布测量原理。通过上述测量可以全面地考察敏感器表面材料对不同光谱成分的反射能力,以及光辐射在材料表面的反射情况。结果表明,敏感器表面材料在入射和反射角大于60°的近红外区(波长为800~2500nm),敏感器表面材料的反射辐射能量明显升高了。在紫外至可见光区(波长为250~700nm),在入射和反射角小于60°的条件下,反射辐射能量很低。更多还原

【Abstract】 The measurement principle of the surface material property of spatial attitude sensor is introduced,including spectral diffuse reflectance and the relative reflectance distribution in space.The reflectance distribution of the sensor surface material can be obtained by measurement based on the two principles.The conclusion shows that the surface material reflected radiance of spatial attitude sensor rises distinctly,when the incidence and reflectance angles is over 60 degrees in near infrared areas(800～2500nm).If the incidence and reflected angles are all less than 60 degrees,the reflected radiance is lower in UV and visible area(250～700nm).更多还原
