Paper Abstract

Fibre modal noise is a photometric uncertainty in a spectrographic resolution element found in high dispersion, high signal to noise spectra. This paper describes how the noise manifests itself and the theory used to describe it. Using a rigorous modal coupling analysis we then show the theories used to date must be called into question due to the changes in the statistics of modal noise with changes in the modal power distribution which occur with arbitrary illumination of the fibre.
