Abstract

A technique for interrogating multiplexed fibre Bragg grating (FBG) sensors using an arrayed waveguide grating (AWG) is described. The approach considerably extends the sensing range from that achieved previously, while providing a strain resolution of 17nevHz at 30 Hz.

Uncontrolled Keywords: interrogating multiplexed fibre Bragg grating sensors, arrayed waveguide grating
