摘要 为实现大尺寸范围内的坐标跟踪测量,研制了一种小型激光跟踪测量系统。设计了光机电一体化的机械结构,实现减小系统体积与提高抗干扰能力。设计了系统的光学模块,通过优化基于位置敏感探测器的目标偏差量采集部分的光路,实现目标允许最大偏差量的增大。通过开展位置敏感探测器的标定实验,完成位置敏感探测器的线性区间与偏差比例系数的测量,为跟踪控制算法开发提供了关键参数。进行了跟踪控制模块的设计,并完成跟踪控制算法的开发,实现系统的快速跟踪测量。开发了系统三维可视化测量软件,实现用户对系统与目标的空间位置及运动状态的实时掌控。实验结果表明,系统的跟踪稳定性与位移分辨力分别为20μm和40μm,系统的跟踪速度最高可达480mm/s,加速度最高可达506mm/s2,跟踪距离范围不小于70m,具有三维坐标测量与三维可视化功能,与现有跟踪仪相比具有体积、重量以及测角范围上的优势,具有良好的跟踪性能与应用前景。

Abstract:In order to realize coordinate tracking and measuring in large size range, a small laser tracking and measuring system with small volume and light weight is developed. The mechanical structure of opto-mechatronics is designed. The optical module, mechanical structure and electronic control module are integrated to reduce the volume of the system and improve the anti-interference ability. The optical module of the system is designed, and the maximum allowable deviation of the target is increased by optimizing the optical path of the acquisition part of the target deviation based on the position sensitive detector. Through the calibration experiment of position sensitive detector, the linear interval and deviation ratio coefficient of position sensitive detector are measured, which provides key parameters for the development of tracking control algorithm. The tracking control module is designed, and the tracking control algorithm is developed to realize the fast tracking measurement of the system. The 3D visual measurement software of the system is developed to realize the real-time control of the spatial position and motion state of the system and the target. The experimental results show that the tracking stability and displacement resolution of the system are 20μm and 40μm respectively, the tracking speed of the system can reach up to 480mm/s, the acceleration can reach up to 506mm/s2, the tracking range is no less than 70m, and the system has 3D coordinate measurement and 3D visualization functions. At the same time, compared with the existing tracker, it has the advantages in volume, weight and angle measurement range, and has good tracking performance and application prospects.
