Paper Abstract

The method of measuring rotating angle with double-frequency laser and wedge-plate interference based on the principle of equal-thickness interference is discussed in this paper. It makes good use of the features of good standing-interference and high sensitivity of double- frequency laser and turns the variation of rotating angle into the variation of interference fringes, so it makes measuring rotating angle with higher precision possible. It not only can determine the rotating direction automatically but also has the features of continuously measuring within 360 degree(s) and the unvarious precision of measuring angle at a higher rotating rate. It has regular theoretical and applied value.
