A multiplexed network of optically powered, addressed and interrogated hybrid resonant sensors

Abstract

It is possible to exploit the advantages of both optical fibre and electronic technologies by the use of a hybrid optical fibre sensor. In this paper a design is reported for a hybrid sensor which employs either a capacitive or an inductive transducer and which can be interfaced on to a fibre optic network of other similar sensors in a multiplexed configuration. The sensors are powered, addressed and interrogated by light signals from the network, and return their data optically. © 1995, All rights reserved.
