摘要：

A new technique for obtaining both time delay and reflectivity as a Function of wavelength within a long fibre Bragg grating is presented. A narrowband wavelength-tunable reflector with a 0.18nm bandwidth is used to select the interrogation wavelength, while optical coherence-domain reflectometry is used to obtain the time delay with better than 2ps accuracy.
