介绍了基于多边法原理的四路激光跟踪干涉三维坐标测量系统,包括系统的工作原理、冗余特性、激光跟踪干涉仪、新型目标靶镜、系统的布局及实验结果等,并进一步指出下一步的工作。实验表明,在距跟踪干涉仪 800 mm远处700mm×600 mm平面范围内,系统三维坐标测量不确定度为0.0620 mm。

The four beam laser tracking interferometer system for three-dimensional coordinate measurement is introduced including the principle of measuring system, the redundancy technique, laser tracking interferometer, a new type of target retroreflector, the optimal arrangement of system and the experimental results. The future work is also pointed out. The experimental results show that four beam laser tracking interferometer system has achieved an accuracy of 0.0620 mm on a 700 mm×600 mm plane located 800 mm away from the trackers.
