Abstract :
The problem of modal noise is often encountered in high resolution spectrograph and in high speed communication fiber links. The experimental approach proved to be a deep mean of investigation of this problem, and it is a good starting point to try to understand and attenuate this source of noise. Through the observation of the spectrum image of known light source, and the comparison between a set of spectrum images, the modal noise has been clearly highlighted.
