  • Abstract
    The topology of a partially developed speckle field is studied using interference techniques. It has been shown that formation of interference forklets in the field gives evidence of changes in the field topology, being the diagnostic sign of transition from a planar Fraunhofer diffraction pattern to a three-dimensional pattern of a diffraction catastrophe.
