An adaptive method for determining the type and magnitude of aberration in a wide range is
proposed on the basis of an optical processing of the analyzed wavefront using a …

Recognition of the types of aberrations corresponding to individual Zernike functions were
carried out from the pattern of the intensity of the point spread function (PSF) outside the …

In this paper, we investigate a wavefront sensor based on the optical expansion of the
analyzed field in the basis of Zernike functions using a multichannel diffractive optical …

In this paper, we study the possibility of forming beams with a scalable wavefront. To multiply
the wavefront with a scale factor, it is proposed to use a combination of the wavefront …

The significance of an autocollimator in angular metrology cannot be overestimated: in many
countries, it is either included as part of the primary plane angle standard or is involved in …

This article explores the possibility of improving the detection of spatial anisotropy and
visualization of weak wave aberrations when the lens is supplemented with a diffractive …

It is known that the astigmatic transformation is used to analyze the topological charge of a
vortex beam. In this paper, to implement astigmatic transformations of vortex beams, a …

This paper presents a study to investigate how the orthogonality property of Zernike modes
gets modified as a light beam carrying the mode in its phase propagates through free space …

In the work, the calculation and study of diffractive optical elements (DOE) for the formation
of a diffraction-free beam in the form of a thin light sheet, which can be used in planar …

In this paper, we study how a propagating laser beam carrying Zernike mode aberrations in
its phase profile undergoes divergence due to diffraction. We first numerically simulate the …
