Laser Alignment Techniques for Simultaneously Measuring Five Degree-of-freedom Deviations of the Object
摘要
Abstract
An optical measurement system has been developed for the simultaneous detection for five degree-of-freedom (DOF) deviations of the object. The measuring system designed bases on laser holographic technique, laser alignment technique, laser drift compensation technique and magneto-optic modulating technique where a single laser beam is used as datum line. This measuring system is applied to multiple degree-of-freedom alignment and measurement of fine deviation, and it carries out the automatic testing in a deformation of machine tool, or the loaded axon in a strain wind tunnel balance. Through actual calibration and measurement, the resolution of the system is estimated to be 4 μm for linear displacement error measurement and better than 2″ for angular error measurement with a 1 m offset between laser and a photoelectric receiving target.
