Speckle-pattern visibility of light transmitted through a multimode optical fiber

Abstract

We show that the reduction in visibility of the speckle pattern obtained from laser light that has been passed through a step-index light guide can be found from a knowledge of the model dispersion of the guide, and the bandwidth of the laser beam.
