Abstract
We propose a simple technique for the estimation of the local inclination angle of the helical wave fronts, and thus the direction of the transverse energy flux, in beams with embedded optical vortices. It is based on the analysis of the evolution on propagation of the asymmetric diffraction pattern produced by a single-slit aperture.
