摘要：

An investigation on the application of fiber Bragg gratings for the interrogation of interferometric low-finesse Fabry-Perot cavities is reported. The proposed scheme is based on the generation of two quadrature phase-shifted signals that allows the recovering of the change in the cavity length. Besides being totally passive, this technique offers a high degree of flexibility and has the potential to be used in the interrogation of very short cavities.
