| Abstract: | The working principle of non-contact optical measurement system for testing the scanning characteristic parameters of the scanner was presented.By use of large scale one-dimensional linear Position Sensitive Detector (PSD) the scanning scale frequency velocity uniformity and time availability were achieved.By use of the small scale two-dimensional PSD and long optical distance the static and dynamic zero repeatability can be measured.By use of semiconductor laser and cylindrical lens the parallelism between the scanning motor shaft and the mirror surface was achieved.The function of self-calibration of the system parameters was realized by using magnetic strip and arc part of mechanical structure. |
