Paper Abstract

The commercialization of optical fiber sensors in smart structure applications largely depends on the development of a multi-sensor system, capable of simultaneously monitoring different optical fiber sensors. Efficient multi-sensor systems can be realized through multiplexing arrays of sensors within a system, reducing the number of input/output information channels between the support electronics and optical sensors. We demonstrate a sensor system, comprised of four multiplexed extrinsic Fabry-Perot interferometers, that uses a code division multiplexing technique to address each sensor. Qualitative measurements of strain and temperature, obtained with this multi-measurand multiplexing system, and an evaluation of crosstalk between sensors is presented.
