摘要

In this paper, a six-degree-of-freedom (6DOF) error measurement system based on geometric optics is proposed for linear stages. This measurement system uses an additional linear stage that drags the sensor onto the stage so that the light spot projected on the sensor moves back and forth with the moving stage. This method achieves long-range 6DOF measurement. Compared with commercial laser interferometers, the proposed measurement system has the advantages of a lower cost, a simpler structure, and the capability of measuring 6DOF errors simultaneously. Zemax software was used to simulate the relationships between the 6DOF errors and the values of position-sensitive detectors. MATLAB software was then used to construct the forward and inverse mathematical kinematic models of the optical paths and simplify the models through curve fitting. Finally, to address installation and manufacturing errors, a reverse kinematic mathematical solution was obtained through the use of a six-axis Stewart platform. The proposed measurement system was experimentally implemented on a commercial linear stage to measure the 6DOF errors and verified against results obtained with a commercial interferometer and electronic level.
