Abstract
Fabry-Perot interferometers have attractive features for use in fiber optic sensors. However, they suffer from undesirable amplitude modulation introduced as a result of coupling losses due to mirror absorption, mirror tilt, curvature of the fiber end-face, fiber mirror separation and splice losses. In addition, non-linearities of high finesse Fabry-Perot interferometers require special readout techniques. A method using digital signal processing is proposed which is able to solve the problems caused by the non-linearities, the directional ambiguities and the coupling losses. This method is demonstrated by using a fiber optic Fabry-Perot interferometer for the measurement of magnetostriction.
