Abstract
We present the results of the experimental formation of contour vortex fields, based on optics of spiral light beams with diffractive phase elements using binary amplitude—phase masks and phase holograms with symmetric and asymmetric grating line profiles. These methods are compared in diffraction efficiency and quality of obtained light fields.
