| Abstract: | We have obtained the quantitative relation Moire fringe spacing corresponding to different structure of tangential grating pair by theory analysis.Based on this,a pair of gratings were designed,and applied to practical measurement.The results indicated that the calculation from our formula were consistent to the data of practical measurement,which had great benefit for extending the space of photoelectric sensor arrangement and improving measurement resolution and precision in position subdivision technique. |
