| Abstract: | The signal processing system for the compensative fiber optic Fabry-perot interfer- ometer is presented. principles and circiuts of the three methods used for the micro-displacement measurement are proposed, i. e. the transmission pesk interval mehtod. the light plaus amplituide of base wave method, and the phase detection method. The measuring results show that the firt methof has a maximum sensitivity of 0.26 * 10 m/s and the second method has its maximum sesitivity of 2.38 * 10 m/v. |
