| Abstract: | This paper describes a novel accelerometer based on wavelength scanning Fabry Perot interference accompanied with the traditional accelerometer using the properties of fiber optical sensor . In the system designed by the authors we get the high resolution. Then we analyze the mulit beam interference which effects the dual beam interference in the FPI cavity. The result from the experiment shows that this kind of sensor is rather sensitive to the microdisplacement (or acceleration) resulting from vibration. |
