A fiber optic sensor probe, with two low-finesse Fabry-Perot cavities
enabling the determination of displacement (in the range of a typical
diaphragm pressure sensor) and temperature, is described. The sensors
are connected in a reflective array network and their status is read u
sing coherence tuned sensing based upon a multimode laser diode at 1.3
mum wavelength. Data are presented which show the resolution and line
arity of the sensors for the measurement of displacement and temperatu
