Design study of fiber-optic based Fabry-Perot type interferometric sensors using low-coherence signal recovery

摘要

A detailed design study is presented as a guide in the design of fiber-optic-based Fabry-Perot type interferometric sensors using low-coherence signal recovery. Several configurations using Michelson and Fabry-Perot type interferometers as the local receiving interferometer for transmissive and reflective type Fabry-Perot sensing interferometers have been investigated. Optimum design parameters are recommended for the use of the different configurations.
