Achromatic diffractive lens limits [PDF]

open access: yes, 2020
Abstract Over the recent years, there have been many reports of achromatic metalenses and diffractive lenses. However, very few (if any) practical applications of such achromatic flat lenses have been demonstrated, which raises questions about the potential of these lenses to provide solutions for real world cases which involve broadband ...

Learning Wavefront Coding for Extended Depth of Field Imaging [PDF]

open access: yes, 2020
Depth of field is an important factor of imaging systems that highly affects the quality of the acquired spatial information. Extended depth of field (EDoF) imaging is a challenging ill-posed problem and has been extensively addressed in the literature ...

ADVANTAGES OF DIFFRACTIVE OPTICAL ELEMENTS APPLICATION IN SIMPLE OPTICAL IMAGING SYSTEMS [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2015
The paper deals with the influence of diffractive optical elements on the optical aberrations. The correction of optical aberrations was investigated in the simple optical systems with one and two lenses (singlet and doublet).

Longitudinal component of the Poynting vector of a tightly focused optical vortex with circular polarization [PDF]

open access: yesКомпьютерная оптика, 2018
We numerically investigated the focusing of optical vortices with the wavelength λ = 532 nm and right-hand circular polarization by using a diffractive lens with the numerical aperture NA = 0.95.

How Reliable Is Pyramidal Wavefront-Based Sensor Aberrometry in Measuring the In Vivo Optical Behaviour of Multifocal IOLs?

open access: yesSensors, 2023
Cataract or refractive lens surgery, along with the implantation of multifocal intraocular lenses (MF-IOL), enables a complete range of functional far, near and intermediate vision.

Multiwavelength polarization insensitive lenses based on dielectric metasurfaces with meta-molecules [PDF]

open access: yes, 2016
Metasurfaces are nano-structured devices composed of arrays of subwavelength scatterers (or meta-atoms) that manipulate the wavefront, polarization, or intensity of light.
