Abstract

A prototype nanometer resolution multiplexing system, capable of multiplexing up to 32 fiber-optic-based extrinsic Fabry-Perot sensors with similar optical path differences for quasi-static absolute measurements has been developed. It is the first time that such a multiplexing system for use with a large number of point sensors has been demonstrated. Several prototype sensor have been incorporated into the network and demonstrated. A range to resolution of better than 10⁴:1 has been achieve. It was also demonstrated that the sensors in the network can be interchanged easily. This instrument is easy to use in practice for multiparameter measurement.
