Abstract
We present the fabrication, characterization and encapsulation of a fibre optic temperature sensor based upon a micro Fabry-Perot (F-P) cavity. The F-P cavity is formed between a reflective in-fibre metallic splice and the air-fibre boundary at the end of the sensor. A change in temperature modifies the optical cavity length and this is observed as a shift in the reflected interference spectrum. The temperature resolution of the sensor is <10 °C. The sensor can reliably operate for high temperature measurement up to 1000 °C. Furthermore a sealed off capillary is used to avoid strain transfer to the sensor in embedded applications.
