Phase Filters for 3D Localization of Point Light Sources

The work relates to the engineering and research of phase filters for three-dimensional localization of point light emitters. These phase filters form a light field having two clearly visible maxima in their intensity distribution (i.e. two-lobe fields). By means of numerical simulation, the influence of the amplitude and phase distortions of the wave front of the illuminating beam on the two-lobe field formation has been studied in the work. Keywords: spiral light beams, amplitude distortions, phase distortions, threedimensional localization, two-lobe field.
