摘要

由于无衍射光莫尔条纹技术具有高的对心分辨精度和适用于长、短 距离测量的特点，在此技术的基础上研制了激光准直跟踪和定位测量系统。它具有抗强光干 扰和抗机械振动的特点，并具有高的定位、定向精度（0.12μm/5m）。%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,anew 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．
