摘要

Characterization of the spatial chirp of a strong (>50%) fiber Bragg grating has been achieved using OFDR at the harmonic (780nm) grating wavelength. Because this grating is weak, a simple Fourier transform inversion of the reflection spectrum may be used to determine the spatial characteristics of the grating.
