摘要
由于被测对象相距较远, 高精度的公共测量基准难以建立, 因此大尺寸空间角测量的难度较大。为了解决大尺寸条件下空间角的现场测量问题, 提出一种基于惯性基准的大尺寸空间角测量方法。首先, 阐述了大尺寸空间角的测量原理并且设计了测量系统。然后, 对测量系统中基于二维振镜的光轴指向不确定度进行了研究, 重点分析了各类误差对光轴指向不确定度的影响。最后, 利用蒙特卡洛仿真对各项误差所引起的光轴指向不确定度进行评定, 为光轴跟踪装置的误差分配及其指向精度的现场评估等工作奠定了基础。
Abstract
Because measured objects are far away, it is difficult to establish a high accurate common measurement reference in the measurement of large spatial angle. In order to achieve the large-scale spatial angle measurement conveniently, a novel large spatial angle measurement method based on inertial reference was proposed. Firstly, the measuring principle of large spatial angle measurement was explained in detail and the measurement system was designed. Meanwhile, the pointing uncertainty of optical axis based on the two dimensional galvanometer in measurement system was studied and the influence of different errors on optical axis pointing was analyzed. Finally, the pointing uncertainty of optical axis caused by different errors was evaluated using Monte Carlo simulation. The research can lay a foundation for error allocation and pointing accuracy evaluation of the measurement system.
