A new method for large shaft alignment was proposed based on visual laser technology and PSD (position sensitive detector) technology. The benchmark beam of light is generated by semicon?ductor laser and received by light targets with PSD. Finally the measure of shaft center-line alignment is finished by optimum algorithm. Through simulation experiment, it is comfirmed that the detecting principle is correct and the method has some advantages such as quick and easy operation, reduces wear and tear of large shaft and offers a new idea for shaft calibration and detection.
