Quantum Theory of Superresolution for Two Incoherent Optical Point Sources
Physical Review X, 2016 Rayleigh’s criterion for resolving two incoherent point sources has been the most influential measure of optical imaging resolution for over a century. In the context of statistical image processing, violation of the criterion is especially detrimental ...

A novel heuristic Morlet wavelet neural network design for the painlevé equation-II arising in nonlinear optics [PDF]
Scientific ReportsThe current investigations present the novel structure of Morlet wavelet neural network (MWNN) for the numerical solutions of Painlevé equation-II arising in nonlinear optics. An error based fitness function is constructed using the sense of differential

Electromagnetic Multi–Gaussian Speckle
Optics, 2022 Generalizing our prior work on scalar multi-Gaussian (MG) distributed optical fields, we introduce the two-dimensional instantaneous electric-field vector whose components are jointly MG distributed.

Three-Dimensional Photon Counting Optical Encryption With Enhanced Visual Quality and Security Level
IEEE Access, 2021 In this paper, we propose three-dimensional (3D) photon counting double random phase encryption (DRPE) with enhanced visual quality and security level. Conventional 3D photon counting DRPE can quickly encrypt the data by using the 4f optical system and ...

Experimental demonstration of singular-optical colouring of regularly scattered white light [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 Experimental interference modelling of the effects of colouring of a beam traversing a light-scattering medium is presented. It is shown that the result of colouring of the beam at the output of the medium depends on the magnitudes of the phase delays of

Method of Estimation of Turbulence Integral Parameters
Applied Sciences, 2021 The optical effects of turbulence are directly related to turbulence integral parameters, which are integrals of the refractive index structure constant over a whole path with different path-weighting functions (PWFs).
