Author:Belyi, VN; Kazak, NS; Khilo, NA; Forbes, A; Ropot, PIDate:Aug 2009The spectrum of spatial frequencies (SFS) of Bessel beams properties emerging at their spatial localization is investigated. The case, when limiting aperture has a circular shape and a center at any distance from the optical axis, was studied. ...Read more
Author:Belyi, VN; Kazak, NS; Khilo, NA; Forbes, A; Ropot, PIDate:Nov 2011In this paper the authors consider the angular spectrum of an apertured Bessel beam when the aperture is circular and shifted laterally with respect to the optical axis. Since the perturbation of the resulting angular spectrum is due to a ...Read more
