Comparison of Accuracy in the Determination of Optical Vortex Coordinates by Different Methods
Two algorithms for the determination of optical vortex coordinates are considered. In the first one, the vortex is found by branching of interference pattern fringes; in the second one, as a result of processing of the wavefront gradient distribution. It is shown that both algorithms allow one to re...

| description | Two algorithms for the determination of optical vortex coordinates are considered. In the first one, the vortex is found by branching of interference pattern fringes; in the second one, as a result of processing of the wavefront gradient distribution. It is shown that both algorithms allow one to record the coordinates with a high accuracy; in addition, it is possible to determine shifts of singular points appearing as a result of radiation diffraction. |
