| Zusammenfassung: | An angle comparator for precision angle measurement is presented, which used the equal-division-averaged (EDA) method to self-calibrate the scale errors of a divided circle. The angle comparator mainly consists of an air bearing, friction motors, and a self-calibratable angle encoder. Using the air bearing and friction motors, we can generate the angular position with the resolution of less than 0.005". The divided circle of the angle encoder has 64800 signal periods within 360° and the final reading resolution is about 0.005". Through the self-calibration procedure based on the EDA method, the scale error can be effectively compensated. |
