Abstract
We propose a method to reconstruct the grating period in fiber grating structures from the field reflection coefficient or the related impul se response. The method is based on the joint time-frequency signal an alysis and uses the Wigner-Ville and the spectrogram distributions. Re sults show good agreement between exact and reconstructed functions.
