Abstract

A new dual wavelength digital spatial domain multiplexing technique for optical fiber sensor array is reported. It can integrate a large number of sensing fibers and as well as dual- wavelength method into a simple, robust and low cost system. It greatly enhances the capacity of tracing fast varying measurands and the absolute measuring range of strain with the digital spatial domain multiplexed sensor system. Preliminary experiments have shown the feasibility of the technique.
