Abstract: Non-diffracting beams and Moire fringe technology is able to work in short,middle and long distance with high measuring resolution.Based on this phenomenon,a new collimating tracking, positioning laser system is developed.The system is highly immune to light vibration and mechanical vibration with high positioning accuracy of 0.12μm/5m.
