Paper Abstract

A temperature Level fiber Optic transducer based on a fiber grating-shape Memory Alloy wire structure (LOMA) is presented in this paper. The basic sensors system works as an on/off optical device: only output light is offered by the device when the structure temperature (T) is over a given temperature level (T>TL). The proposed fiber structure can be used as point or as quasi-distributed sensors systems exploiting its optical multiplexing capacities. The simple and cost effective device is successfully demonstrated in the laboratory.
