摘要
径向哈特曼像质检测系统(RHTS)是一种新型的大口径光学检测系统,在室内不用大口径标准平面镜就可以实现光学系统的检测。目前,RHTS存在测量时间长、图像采集数据量大、以及在测量过程中,温度、噪声等周围环境的不稳定因素对系统的测量结果影响严重等问题。在测量大口径光学系统的过程中,基于对该系统控制流程的分析,本文提出了动态测量控制方案,设计出满足该动态测量所需要的控制电路,并采用新的数据采集处理方法,实现了径向哈特曼的快速动态测量,减少了系统测量时间。
Radial-Hartmann wave-front Test System （RHTS） is a new measurement sYstem for large-aperture optical system. It can be used for the measurement of the optical system without a large-flat mirror in the room. Currently, this system has some problems such as long time for measurement, large mount of image acquisition and the instability of the surrounding environment such as temperature and noise. During the course of the measurement for large-aperture optical system, based on the analysis of the control flow, a control method for dynamic measuring is put forward, a control circuit for the dynamic measuring is designed. And a fast dynamic measurement of the RHTS is achieved and the test time is decreased with a new method of data collection and calculation.
