Abstract

A prototype single-mode fiber-based Fizeau interferometric medical temperature sensor using coherence reading signal processing and mechanical amplification in the sensor design has been optimally designed and constructed. A measurement resolution of 0.006 degree(s)C and a 1% of span linearity over a temperature range of 27.3 approximately 62.5 degree(s)C have been achieved. This miniature sensor is expected to be a practical approach for most medical applications after further engineering.
