Abstract :
For a particular source and fibre, frequency correlation effects determine speckle contrast. For a specified degree of spatial filtration, speckle contrast in turn determines modal noise statistics. The measurement and analysis is reported of the correlation of two multimode fibre speckle patterns as a function of their source frequency difference.
