| Abstract: | A method based on position sensitive detector （PSD） to measure the ditch and yaw error and straightness error of long linear guide rails simultaneously is introduced. The measurement principle is analyzed and validated. The mathematical model of the ditch and yaw angle as well as straightness error after correction of laser space angle are built. The various factors that affect the measurement process are discussed and some measures are taken to eliminate the influence. |
