An optical system is considered that ensures the concentration of radiation from an LED emitting within a hemisphere onto a near-field illuminated area. The system is proposed to consider such a system as a composition of two zones — the central zo

The paper considers the optical systems of virtual reality, which use an optical wedge to eliminate or reduce the conflict of convergence and accommodation (vergence- ccommodation conflict, VAC). The inclined surfaces of the optical wedge introduce s

The paper considers a design method for a side-emitting lens working with a single LED source and providing a narrow light beam in the horizontal direction within 360°. The authors deal with the composing method in the design, which is usually used

Multiple-window acousto-optic filtering of wide-band (white) light allows to control chromaticity of radiation in the visible range, which allows to use a system consisting of a source of radiation and an acousto-optic filter for colour reproduction

Ground-based and Airborne Telescopes VIII.
Currently, numerous projects for the study of both outer space and the Earth's surface use mirror optical systems, since they allow working in a wide spectral range. As a rule, three-mirror anastigmats (TMA) are used, however, it is possible to corre

We demonstrate a simple design method to be applied in designing of LED collimating systems. In the first stage, we have considered several zones in a lighting beam and analyze their aberration properties, in the second stage we combine zones into a

Optical Design and Testing X.
The development of devices based on an acousto-optical filter (AOTF) is widespread. It is essential to be able to accurately simulate acousto-optic diffraction when modelling optical systems that include AOTF. However, the AOTF model is not a built-i
