硅油对遥感仪器镜面污染的研究

STUDY OF Si-OIL CONTAMINATION ON MIRROR OF REMOTE SENSING INSTRUMENT

对被硅油污染的镜面进行了光谱测试,测得了硅油的红外吸收波段及吸收系数。实验证明吸收波段上的油膜透过率随着油膜厚度增加呈指数衰减。

The spectra of Si-oil which contaminated the mirror were measured. The infrared absorption band and absorption coefficient of Si-oil were obtained. The experimental results demonstrate that the transmissivity of oil-film in the absorption band is exponentially decreased with the increase of the film thickness.
