Abstract
Coating is one of the most effective ways to attenuate straylight. The absorbance of seven kinds of coatings suppressing stray-light, which are often used on inner wall of space remote sensor, is tested in this article. After testing, author find there are many differences between these coatings. The best coating, which is selected from the seven coatings, has very high absorbance through visible and near-IR waverange(0.4~2 μm). Using this coating as the inner coating of space remote sensor, author simulate the PST(θ) as the off-axis angle θ changing. Results show that when off-axis angle θ is more than 10°, the PST can reduce to 10-10 at least.
