Abstract:
Several methods are available for generating radially symmetric figures using DOEs. Conical axicons in combination with spherical lenses [1] and binary axicons [2] are usually used to focus coherent light into a narrow ring. A narrow light ring in the focal plane is understood as a ring with the width less than the Fraunhofer diffraction limit for a conical wave with the limited aperture diffracted by the DOE [3].
