Abstract

A distributed temperature sensor is presented which uses a chirped Moiré fibre Bragg grating to give a thermal resolution of 0.2°C with a spatial resolution of 164 μm. The wavelength sensitivity of the device is 0.01 ± 4 × 10-4 nm/°C. Such a sensor has biomedical and industrial applications where accurate measurement of location and intensity of temperature is essential. The sensor may be used as a one- or two-dimensional temperature monitor, depending on the configuration. © 2004 Elsevier B.V. All rights reserved.
