高功率激光装置靶场光学系统的误差分析

Error Analysis for the Optical System of Target Area on High Power Laser Facility

基于高功率激光装置主激光束精确打靶的需要,应用误差分析方法为装置的工程实施和单元技术的改进提供理论指导。针对装置在每发打靶前多应用自动准直技术来消除存在的误差,而传统的误差分析方法即随机误差和传统误差又未能进行全面系统的分析,提出了新的激光瞄准误差分析方法:静态误差和动态误差的划分。通过对靶场光学系统全面的误差分析,获得激光瞄准精度的普适性公式,并验证了该误差分析方法的正确性和可行性。

To achieve the laser accurately positioning on the target in high power laser facility, the error analysis method is necessary to actualize engineering of the facility and increase the technology of the correlational systems. The automatic alignment control system is mainly designed to establish and maintain laser chain alignment and eliminate the error, but the traditional error analysis method based on both contingency and system errors does not give a comprehensive analysis. So a new error analysis method based on both static and dynamic errors is developed. The optical system in the target area is analyzed with this method and a common equation of target positioning tolerance has been obtained. The satisfaction and feasibility of the error analysis are demostrated.
