Optics Express, 2021 Diffractive optical elements (DOEs) may be used as a single optical component with dedicated functionality (e.g. focusing), or as one of the elements in complex hybrid optical systems to reduce the number of the elements and improve imaging quality. It is desirable to cover DOE’s

Optimal Control of Passive Cascaded Liquid Crystal Polarization Gratings
Applied Sciences, 2023 The incidence angle of a beam entering a liquid crystal variable retarder (LCVR) and the liquid crystal polarization grating (LCPG) is greater when the LCPG is utilized in the quadrature cascade, which reduces the diffraction efficiency.

Diffraction efficiency calculations of polarization diffraction gratings with surface relief [PDF]
Journal of Physics: Conference Series, 2018 In this paper, we evaluate the optical response of a stack of two diffraction gratings of equal one-dimensional periodicity. The first one is a surface-relief grating structure; the second, a volume polarization grating. This model is based on our experimental results from polarization holographic recordings in azopolymer films.

Optical Design of a Slitless Astronomical Spectrograph with a Composite Holographic Grism
Photonics, 2023 In the present work, we consider an optical design of a slitless spectrograph for an existing 0.5 m-class telescope. This design concept has a number of advantages such as compact size, simplicity, and simultaneous coverage of a large field of view.

Energy efficiency of a new trifocal intraocular lens [PDF]
Journal of the European Optical Society-Rapid Publications, 2014 The light distribution among the far, intermediate and near foci of a new trifocal intraocular lens (IOL) is experimentally determined, as a function of the pupil size, from image analysis. The concept of focus energy efficiency is introduced because, in
