Abstract
The letter describes a temperature sensor which employs an intensity-modulation filtering technique to measure the thermally induced change in delay in a length of optical fibre wound on an aluminium cylinder. The sensor response was measured over a temperature range of 10–40°C, and is in good agreement with theory.Keywords
