Performing the laser processing of materials implies the importance of producing the desired
effect on local regions with a predetermined distribution of the beam-power density. The …

Multilevel diffractive lenses (MDLs) have emerged as an alternative to both conventional
diffractive optical elements (DOEs) and metalenses for applications ranging from imaging to …

We demonstrate an inverse designed achromatic, flat, polarization-insensitive diffractive
optic element, ie, a multilevel diffractive lens (MDL), operating across a broadband range of …

A device for visualization of blood vessels in the human skin is presented. A diffractive
optical element is used to locate blood vessels in the skin image. It has been shown that …

Various types of diffraction and plasmonic elements are discussed that provide modern
development of sensors in different applications such as analysis of the mode composition …

In this paper, we considered design of the complex metalens with high numerical aperture. It
proposed to be manufactured in a thin film of silicon nitride. The element represents two …

Further development in the field of creating elements of nanophotonics and diffractive
microoptics with new functional properties requires the improvement of technologies for …

We offer a computer technology for modeling a process of optical imaging with a diffractive
imaging lens. The central idea of the technology is to evaluate the quality of the optical …

The problem with existing flow meters is a relatively high measurement error, which is
associated with a lack of information on the flow profile. In order to create a reference device …

The development of piezoelectric and optical elements from microcells was carried out and
models were prepared for printing on a 3D printer. These designs can be practically used as …
