Abstract
A rotational speed measuring and calibration system based on the Laser Doppler Velocimetry is proposed in this paper. The rotational speed of a motor in the system can be determined by measuring the tangential linear velocity of a rotating reference disc mounted on the motor shaft with a Laser Surface Velocimeter. Measuring deviations caused by manufacturing and mounting errors of the reference disc are analyzed and compensated. Therefore, a measuring accuracy of better than 0.1% is realized.
