Abstract

We describe work on a system able to measure the temperature at a number of points along a single optical fiber probe, designed for in-vivo temperature profile monitoring. The sensing elements are in-fiber Bragg grating sensor and three forms of signal processing have been investigated. System 1 uses interferometric wavelength shift detection with a monochromator providing the WDM. System 2 used a scanning in-line Fabry-Perot filter and system 3 uses a monochromator with a CCD based readout scheme. The performances of the three approaches are compared.
