Not Accessible

Your library or personal account may give you access

Abstract

The multi-reflection crosstalk when combined with the spectral-shadowing effect has been shown to make the interpretation of spectral analysis more difficult in Phase-OTDR sensing system based on weak fiber Bragg grating array.
