TY - JOUR AU - Severin, Piet J. AB - An optical-fibre sensor based on the phase of the signal reflected from a stack of 5i02/Si3N4 layers grown on silica in LPCVD is described in detail. This sensor is an example of a rather straightforward embodiment within the wide range of possible reflection-based optical fibre sensors. The various options allowing more refined solutions matched to the measurement problem are discussed in more general terms. 1.
