Diffraction is a phenomenon related to the wave nature of light and arises when a
propagating wave comes across an obstacle. Consequently, the wave can be transformed in …

This book deals with theoretical bases of the modern optics division concerned with
coherent light fields with singularities characterized by phase uncertainty. Singular light …

We discuss a three-parameter family of paraxial coherent light fields that originate from a
complex amplitude composed of the following four cofactors: the Gaussian beam, a …

This work is an analytical review of the components of modern technology for creating
adaptive optics systems for correcting the distortion of optical waves propagating in a …

One of the main disadvantages of imaging systems is the limited depth of field. We present
the ability of a refractive axicon for imaging with an extended depth of field. We design an …

We present a setup to generate tightly focused Bessel beams that is composed of a half-ball
lens coupled with a relay lens. The system is simple and compact compared to conventional …

We investigate theoretically and experimentally the astigmatic transformations of Bessel
beams at propagation perpendicularly to the c-axis of a uniaxial crystal. The analogy …

Данная работа представляет собой аналитический обзор составных частей
современной технологии создания систем адаптивной оптики для коррекции …

With conventional light microscopy, precision in the measurement of the displacement of a
specimen depends on the signal-to-noise ratio when we measure the light intensity of …

An analytical expression of an elliptical Bessel beam (EBB) is deduced on the basis of the
angular spectrum decomposition (ASD) method, starting from an elliptical Bessel-like profile …
