【摘要】：为了测量水平式激光发射系统激光指向误差,提出了一种天顶范围激光指向远距离检测方法,设计了一个激光方向检测装置,介绍了激光方向检测装置的组成及工作原理,详细介绍了光线折转系统的结构,对指向误差进行了实际测量,获得激光指向误差为5.7″,对检测装置中影响激光指向误差的误差源进行了分析,得到了作为系统误差的视差ε1、检测装置的结构变形误差ε2被消除、检测装置的测量误差主要取决于电视系统分辨率和激光器光轴漂移误差的结论,该检测装置测量的激光指向不确定度为1.87″。外场试验结果表明,通过该检测装置得到的检测结果进行误差修正后,激光发射精度满足使用要求,检测方法直接、简便,检测精度较高,该检测方法可以在工程实际中得到推广应用。
[Abstract]:In order to measure the level of laser emission system of laser pointing error, presents a range of zenith laser pointing long-range detection method, a laser direction detection device design, introduces the composition and working principle of the laser direction detection device, introduces the system structure of the light reflex, the pointing error of the actual measurement, laser the pointing error is 5.7 ", the influence of error in laser pointing error detection device is analyzed, the system error as parallax epsilon 1, epsilon 2 error is eliminated the structure deformation detection device, measurement error detection device mainly depends on the optical axis of laser TV system resolution and error detection of the conclusion. Laser pointing device for measuring uncertainty is 1.87". The field tests show that the results obtained by the detection device for error correction, laser hair The ejaculation degree meets the requirements of the use. The detection method is direct, simple, and the detection precision is high. The detection method can be popularized and applied in the engineering practice.
