The impact on an optical surface by a micrometeoroid gives rise to a specific type of stray light inherent only in the space optical instruments. This causes a double source of light scattering: the impact crater and the ejected contamination. We propose a method of stray light estimation and apply it to the case of the Laser Interferometer Space Antenna telescope. We estimate the backscattering fraction for nominal (4 years) and extended (10 years) mission durations.

由于空间光学中的微小流星体损坏而导致的杂散光估计,应用于LISA望远镜

微型流星体对光学表面的影响会产生仅在空间光学仪器中固有的特定类型的杂散光。这导致了光散射的双重来源:撞击坑和喷出的污染物。我们提出了一种杂散光估计方法,并将其应用于激光干涉仪空间天线望远镜的情况。我们估计了名义(4年)和延长(10年)任务持续时间的反向散射分数。
