| 摘 要： | 为了实现对拼接镜的共焦调整,建立了拼接镜主动光学共焦实验系统。实验中,拼接镜由3块对边长300mm的正六边形子镜组成,子镜为球面,曲率半径为2000mm。采用Shack-Hartmann传感器进行共焦测量,用6个微位移平移台对两块子镜的离焦和倾斜进行调整。每个子镜对应Shack-Hartmann传感器的36个子孔径,用子孔径产生的像点位置偏移计算子镜之间的共焦误差。通过微位移平台调整,可控制子镜的轴向离焦误差优于1μmrms,倾斜误差在两维方向上均优于0.02″rms。实验表明,该方法适用于大型拼接镜面望远镜的共焦标定和实时调整。

| Abstract: | A co-focus experiment system of segmented-mirror active optics is built to realize the co-focus fine-tuning of a segmented-mirror. In this system, the segmented-mirror consists of three hexagonal submirrors with 300 mm side to side, and the shape of each submirror is spherical with 2 000 mm radius. A Shack-Hartmann sensor is used for co-focus measurement, and six micro-displacement translation stages in this system are used for adjusting the co-focus and tilt of the two sub mirrors. Each sub-mirror correspo... |
