In-line Fiber Fabry-Perot Interferometer with High-Reflectance Internal Mirrors

Operation of fiber Fabry-Perot interferometer (FFPI) temperature sensors from -200°C to +1050°C has been demonstrated [1]. These sensors used internal mirrors produced by a fusion splicing technique. Internal-mirror FFPIs have been embedded in graphite-epoxy composites and polymers, where they were used to sense temperature [2] and ultrasonic pressure [3].
