Abstract

Rotation of the output speckle-pattern of multimode fiber was experimentally observed when the input radiation frequency was sweeping. Variations of the speckle-pattern were studied theoretically by means of the correlation analysis. The effect is confirmed and is shown to depend on the conditions of the guided modes excitation.
