| Abstract: | In this paper,a technique by which azimuth can be passed vertically between two parts without connection is expatiated.And the precision of the technique is analyzed.Because the physical characteristic of polarization-light is utilized in this technique,the domestic localization in collimation is broken through on principle.By magnetooptic modulation,the measuring precision of this collimation technique is improved and the repeated measuring precision of show-set is 3σ≤10″. |
