摘　　要：介绍了一种使用激光光束作为基准线来测量直升机传动装置同轴度的新型方法,详细阐述了该系统的工作原理、软硬件实现方案。在系统的硬件设计中,通过准直透镜和聚焦透镜的引入,提高了系统的稳定性和测量精确度;测量采用基于图像处理的软件读数,极大地降低了维修人员对测量工作经验的依赖,提高了工作效率。现场试用证明系统可以及时、准确地测量出直升机传动系统的同轴度。A novel method of measuring the coaxial degree for the helicopter transmission with laser beam is presented. By introducing collimation lens and focusing lens, the stability and accuracy of the measurement system are improved, the software design can greatly decrease reliance to measuring working experience and improve working efficieney for engineers. Using this system, coaxial degree of the helicopter transmission can be measured fast and accurately.
