Operation Manual for Measurement and Discrete Layer Peeling of Fibre Bragg Grating Spectra; Technical note

摘要

This document is a manual detailing the operation of an interrogation system for measuring the complex reflection spectrum of a Bragg grating. The manual also describes custom-designed software for deconvolving this data to determine the pitch profile of the grating by using a discrete layer peeling technique. This information can be used to determine the strain profile experienced by the grating in cases where the grating length spans the localised strain field.
