Paper Abstract

The exposure of multiple Bragg gratings into a single optical fiber has been demonstrated. As sensors of strain and temperature, these devices promise an architecturally efficient means to conduct quasi-distributed measurements with an array of discrete gages. Such a configuration can have great benefit when embedded within composite structures. This paper will present instrumentation concepts and results from initial laboratory work to develop methods for multiplexed strain and temperature measurements using Bragg grating sensors.
