Abstract

We report the result of investigation of the screw, edge and mixed edge-screw dislocations of wavefront in monochromatic light waves. Methods for the experimental determination of the topological charge value and helicity of screw dislocation are elaborated. By use of computer- synthesized binary gratings waves with edge, mixed screw-edge and anisotropic screw dislocation were obtained and studied experimentally.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
