摘要：

This paper explores a kind of new method of high-precision non-contact measurement of rotate speed, to acquire data with a laser CCD displacement sensor, and separate the low-frequency signal and high-frequency noise of the signal with the small-wave multi-frequency analysis method, to pick up the frequency for the separated low-frequency signal as the Nquist sampling theorem, to get the rotate speed to be measured. The experiment has proved this measurement method has the very good feasibility and effectiveness.
