Abstract.
Spatial structure of optical vortex helical wave fronts is for the first
time directly tested using various interference arrangements and precise
measuring techniques. Experimental data are compared with simulation results.
On this base, advantages of interference technique of any kind for testing
of optical vortices in solving the specific problems are revealed.
Keywords: singularity, optical vortex, helical wave front.
