Results show that the angle of two intensity profiles can be used to describe the self-healing ability of arbitrary beams as the reconstruction distance for quantitatively describing theSelf-heating ability of Bessel beam.Abstract:
Quantitative description of the self-healing ability of a beam is very important for studying or comparing the self-healing ability of different beams. As describing the similarity by using the angle of two infinite-dimensional complex vectors in Hilbert space, the angle of two intensity profiles is proposed to quantitatively describe the self-healing ability of different beams. As a special case, quantitative description of the self-healing ability of a Bessel-Gaussian beam is studied. Results show that the angle of two intensity profiles can be used to describe the self-healing ability of arbitrary beams as the reconstruction distance for quantitatively describing the self-healing ability of Bessel beam. It offers a new method for studying or comparing the self-healing ability of different beams.read more

Generation and self-healing of vector Bessel-Gauss beams with variant state of polarizations upon propagation.
TL;DR: A generalized model for the creation of vector Bessel-Gauss (BG) beams having state of polarization (SoP) varying along the propagation direction is proposed and the self-healing capability of spatial SoP information is evaluated.

TL;DR: In this article, it was shown that diffraction-free beams may not only reconstruct themselves after hitting an opaque obstacle but also, for example, Gaussian beams, by comparing the amplitudes, as opposite to intensities, of the original beam and the obstructed one.

TL;DR: The influence of the obstacle position separation from the source on the self-healing capacity of partially coherent beams is studied using Hermite-Gaussian correlated Schell-model beams as a case in point and it is established that the shorter the distance between the obstacle and the source plane and the longer the Distance between the obstacles and the observation (receiver) plane, the better theSelf- healing capacity.
