Multiplexed, white-light interferometric fiber-optic sensor matrix with a long-cavity, Fabry-Perot resonator

摘要

A long-cavity, single-mode, fiber-optic Fabry-Perot resonator has been used to develop white-light fiber-optic multiplexed Michelson interferometers (MMIs). The MMI matrix is constructed and demonstrated. We also analyzed the capacity of the long-cavity Fabry-Perot resonator multiplexing technique. The experimental results of a 2×2 fiber-optic interferometric sensor matrix are given, and the effects of polarization are discussed.
