Abstract

A combined optical fiber pressure/temperature sensing system based on low-finesse extrinsic Fabry-Perot interferometer (EFPI) in conjunction with a fiber Bragg grating (FBG) for biomedical measurement applications is presented. The sensing probe has 200 μm outer diameter, and is biocompatible, meeting the requirements for the most demanding biomedical applications. High accuracy (1nm/kPa. A white light interrogation system based on spectrometric analysis has been developed which implements several pressure detection algorithms. A measurement campaign has been carried out to validate the proposed system, showing 1mmHg accuracy, air-gap compression linearity, and temperature compensation.
