Description
Summary:A new approach using fiber-based Fabry--Perot interferometry for constructing highly resistant and highly accurate vibration sensors is presented. The application of a diode array makes it possible to acquire a multitude of interference signals which can be classified into pairs of signals fulfilling the quadrature condition. This approach reaches the sensitivity of single-mode optical fiber interferometers proposed in the past while providing a much higher signal accuracy.
