An interferometric device designed to be located in the focal plane of a large astronomical telescope is presented. The prime application is for the forthcoming large space telescope. The device is to perform interferometry on the optical wavefront arising from a single star after it has propagated through the telescope. The concept of a focal plane figure sensor has been experimentally verified by fabricating and testing an operating laboratory breadboard figure sensor. A set of linear independent control equations are derived that define the operations for utilizing a focal plane figure sensor in the control loops for the positioning of the secondary mirror and for the active control of the primary mirror optical figure. A number of scientific experiments that could be preformed with the interferometer are also briefly discussed.
本文介绍了一种设计用于大型天文望远镜焦平面的干涉测量装置。其主要应用是即将推出的大型空间望远镜。该装置将对来自单颗恒星的光波前在通过望远镜传播后进行干涉测量。通过制造和测试一个工作中的实验室实验模型图形传感器，焦平面图形传感器的概念已得到实验验证。推导了一组线性独立控制方程，这些方程定义了在控制回路中利用焦平面图形传感器来定位副镜以及主动控制主镜光学图形的操作。还简要讨论了一些可以用该干涉仪进行的科学实验。
