Abstract

For improved the precision of the measurement result of the gain coefficient and avoid the affection of the optical spectrum analyzer´s resolution and noise, we combined the Hakki-Paoli method with the wavelet denoise and deconvolution process. It was testified from the simulation that this method improve the precision of the gain coefficient measurement. At last, the conclusion was testified from the experiment
