Paper Abstract

It is shown, that spiral interferograms can be used for diagnostics of screw dislocations. The connection between the type of spiral line, the type of defect and the values of wavefronts curvatures of interfering beams is established. The spherical wave is considered as reference wavefront. The results of analysis for isolated dislocation are integrated on case of defects set. It is shown, that the diagnostics of coherent fields with defects as screw dislocation requires the preliminary study of wavefront topology. The outline of execution of such testing is offered.
