中文摘要	光学系统在空间环境条件下的衰变对卫星遥感仪器探测精度有重要影响,漫反射板是星载光学遥感仪器辐射定标的重要工具,本文通过对ADEOS/TOMS和EarthProbe/TOMS仪器漫反射板漫反射率衰变特性的比较,分析研究了原子氧和太阳紫外辐射对漫反射板的影响.结果表明,太阳紫外辐照和原子氧剥蚀引起的漫反射板反射率衰变系数分别为0.00049/h和1.2×10^-17cm^2,但在卫星入轨初期,太阳紫外辐照的影响可增加约4倍.
英文摘要	The degradation of optical sys1nrn. in space environment has an important effect on the measuring precisior.on saelite-bome sensing instruments. The solar diffuser is an important tool of raaiation intensity scaling for satellite-borne optical remote sensing instrnment. In this paper a comparison of the decay of solar diffusers in ADEOS/TOMS and Earth Probe/TOMS, and analyses the effects of atomic oxygen and solar UV radiation on solar diffuser is given. The results show that the decay coefficients of solar diffuser in the wavelength of 360 nm due to solar UV radiation exposures and atomic oxygen erodes are 0.00049/h and 1.2x10-1' cm2 respectively. So the effect of atomic oxygen erodes is about 5 times of solar UV radiation exposures in the altitude of 800 km during the solar activity minimum.For the solar activity maximum, the effect of atomic oxygen will greatly increase. In the early days of satellite orbit, however, the effect of solar UV radiation exposures on solar diffuser may increase about 4 times. It may be due to the contamination.But our analyses havn't find the interaction between atomic oxygen erodes and contamination effect.
