Abstract
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 re.
