摘要
提出用无衍射光和环光栅重叠产生环状莫尔条纹的技术来进行空间直线度测量的技术 ,给出了理论分析、仪器结构和原理实验 ,并对该方法在同时实现高分辨力和大量程直线度测量的可能性 。
A method of spatial straightness measurement by the method of super positioning the non diffracting beam and ring grating to generate moire fringe is proposed.Theoretical analyses,instrument structure and principle experiment are given.Some characters,such as the possibility of maintain high sensitivity and large measurement range simultaneously,resistance to laser bean draft are discussed.
