摘要
本文讨论了基于楔形平板等厚干涉原理的激光楔形平板干涉测量转角的方法。这种方法是将被测转角的变化转换为激光拍频的变化，从而实现转角的高精度测量。它能自动分辨转动方向，在３６０°内可进行角度的连续测量，在较高转速下测角精度基本不发生变化，具有一定实际应用价值。
Abstract The method of measuring rotating angle with dotible frequency laserand wedge plate interference based on the principle of equal thickness interfernce is dis-cussed in this paper. It makes good use of the features of good standing interfernce andhigh sensitivity of double frequency laser and turns the vaviation of rotating angle into thevaviation of interference frings , So it makes measuring angle with higher precision be possi-ble. It not only can determine the rotating direction automatically but also has the features ofcontinuously measuring within 360° and the unvarious precision of measuring angle at higherrotating rate. So it has regular theoretical and applied value.
