An interferometric fringe scanner was used for the Technology Mirror Assembly (TMA) x-ray telescope, built by Perkin-Elmer as a technology demonstration for the Advanced X-Ray Astrophysics Facility (AXAF). We discuss advanced data processing features, implemented during a follow-on project to improve the mirror's midfrequency errors still further. Data processing techniques include interleaving of multiple scans, and optimal smoothing and interpolation of the interleaved data onto a uniform grid. We discuss the underlying mathematics behind the processes, the motivation in terms of recovering the highest possible spatial frequencies from the data, and some sample results.
一台干涉条纹扫描仪被用于由珀金埃尔默公司制造的技术镜组件(TMA)X射线望远镜,该望远镜是作为高级X射线天体物理设施(AXAF)的技术演示而建造的。我们讨论了在后续项目中实施的先进数据处理功能,以进一步改善镜面的中频误差。数据处理技术包括多次扫描的交错,以及将交错数据在均匀网格上进行最优平滑和插值。我们讨论了这些过程背后的基础数学、从数据中恢复尽可能高的空间频率方面的动机以及一些示例结果。
