Abstract

In this paper we propose a novel matrix method for measuring the internal distributed structure within fiber Bragg grating. It bases on the reflection characteristics of short segment of grating and OCDR (optical coherence domain reflectometry) theory, and shows the relationship of the global spectrum characteristics and local internal structure of grating mathematically. Simulation results show that higher reconstruction resolution for FBG can be obtained with the new theory.
