Annular-focus zone lens for increasing the intensities of created Bessel beams
Annular-focus zone lens for increasing the intensities of created Bessel beams
摘要
Abstract
In this paper we proposes a new concept of annular-focus zone lens and its design procedure based on binary optics. An investigation of the diffraction efficiencies and the transverse intensity distributions on the focal plane of the designed annular-focus zone lenses is presented. This special kind of zone lens may be used to increase the intensities of Durnin's diffraction-free beams.
