A method of measuring micro-vibration amplitude with laser is presented. By using the optical resonant characteristic of Fabry-Perot etalon and intensity-comparison lock-in technique of laser, we have completed a measurement with the minimum amplitude of vibration at the order of 10-12 cm under the condition of an ordinary laboratory.
