Paper Abstract

Experimental and theoretical investigations of the use of multi-mode laser diodes in a coupled Michelson: Fabry-Perot interferometer and a novel Michelson: Bragg interferometer for fibre-linked interferometry are reported. These results show that the coherence regions of such diodes can be varied over a large range of optical path imbalance of the interferometers allowing the interference region in fibre optic sensors to be tailored to specific sensor applications.
