Paper Abstract

Formation of light fields with preset intensity is of the interest for different laser applications. Spiral beams optics is the universal method of such fields generation. One of the experimental ways of spiral beams formation is the astigmatic transform of specially realized one-dimensional light field to the intended spiral beam. The presence of phase singularities is the feature of spiral beams. Traditional interference detection of singularities of spiral beams can be inconvenient if the number of isolated zeros located within the low intensity area. It is typically for beams in the shape of closed curves. The same astigmatic transform can also be used for the beams analysis.
