【Abstract】 Applications of redundancy technique in a multi beam laser tracking interferometer system for 3 D coordinate measurement are presented. On the basis of analyzing the principle of laser tracking system, the measurement system is established to be 3/n[G] voting system by using hardware redundancy technique. The redundant measurement system presents many powerful characteristics such as self calibration, recovering the lost information, error compensation and so on. Finally, a conclusion that the redundancy design should be an important principle during the period of the system design is also emphasized.更多还原
