本文介绍了主要由激光准直技术和激光全息五维传感器所组成的空间五自由度定位系统。这种定位系统已成功地用于飞机型架自动安装机和天平自动校验台上,试验结果表明,这种系统动态性能良好,时间常数小,工作范围大,灵敏度高,输出信号强。另外,由于在光路中采用了光束漂移补偿装置,整个系统几乎无需预热时间,工作长期稳定可靠,提高了功效。 This paper introduces a five-DOF positioning system composed of laser collimation technology and laser holographic five-dimensional sensor. The positioning system has been successfully used in aircraft frame mounting machine and balance automatic calibration platform. The experimental results show that this system has good dynamic performance, small time constant, large working range, high sensitivity and strong output signal. In addition, due to the use of beam drift compensation device in the optical path, the entire system almost no need to warm-up time, work long-term stability and reliability, improve efficiency.
