Abstract

A novel temperature sensing system using optical coherence domain reflectometry (OCDR) was presented. A cw low coherence source with a coherence length on the order of 10μm was coupled to a fiber directional coupler and divided into the test arm and the reference arm. The results showed that the peak distance change was a linear function of the temperature of the sensing loop.
