Paper Abstract

It was considered three methods of the computer processing of the spiral interference pattern being the result of two field superposition: the field carrying over an optical vortex and scattered from the optical fiber with a field of a referent fundamental Gaussian beam. The revolving interference pattern was subjected to the computer processing and the coordinates of the spiral center and the parameter of the spiral curvature was defined. As a result of that it was chosen the most optical method and was found that optimal computer inaccuracy of measurements of spiral phase is 0.0115 rad.
