Abstract :
A High temperature probe, based on a miniature fibre optic Fabry-Perot, operational temperature 700degC set by the maximum temperature of the gold plated optical fibre transceiver link used is presented. The probe is interrogated by a tuneable laser at 1300 nm, line width ~90 nm, with a second stage booster amplifier giving a maximum quasi-static output power of ~27 mW. Scanning rates of 1 kHz and 20 kHz for linear and sinusoidal scans respectively.
