摘要
为实现静止轨道遥感仪器的可见光近红外波段星上定标,设计了以太阳作光源,漫反射板作目标的方案。其中,漫反射板的光学特性和空间环境变化是关键技术。介绍了漫反射板的双向反射分布特性,以及双向反射分布函数(BRDF)的测试,进行了漫反射板的空间环境模拟试验。试验结果表明能够满足应用的需要。
In order to realize the onboard calibration for visible and near infrared bands of geostationary sensors,the sun is used as light source to illuminate the PTFE diffuser. The optics characteristics and spatial stability of the diffuser are crucial and essential. The results of bidirectional reflectance distribution function （BRDF） test, vacuum cleaning and UV exposure indicate the scheme is feasible and the diffuser is eligible for future application.
