On design of hybrid diffractive optics for achromatic extended depth-of-field (EDoF) RGB imaging
Seyyed Reza Miri Rostami, Samuel Pinilla, Igor Shevkunov +2
A hybrid imaging system is a simultaneous physical arrangement of a refractive lens and a multilevel phase mask (MPM) as a diffractive optical element (DOE). The favorable properti…
SSR-PR: Single-shot Super-Resolution Phase Retrieval based two prior calibration tests
Peter Kocsis, Igor Shevkunov, Vladimir Katkovnik +2
We propose a novel approach and algorithm based on two preliminary tests of the optical system elements to enhance the super-resolved complex-valued imaging. The approach is develo…
Power-Balanced Hybrid Optics Boosted Design for Achromatic Extended-Depth-of-Field Imaging via Optimized Mixed OTF
Seyyed Reza Miri Rostami, Samuel Pinilla, Igor Shevkunov +2
The power-balanced hybrid optical imaging system is a special design of a diffractive computational camera, introduced in this paper, with image formation by a refractive lens and…
A novel two- and multi-level binary phase mask design for enhanced depth-of-focus
Vladimir Katkovnik, Nicholas Hogasten, Karen Egiazarian
This paper introduces a two-and multi-level phase mask design for improved depth of focus. A novel technique is proposed incorporating cubic and generalized cubic wavefront coding…
Phase retrieval with background compensation in 4f configuration: advanced augmented Lagrangian technique for amplitude object
Artem Migukin, Mostafa Agour, Vladimir Katkovnik
Generally, wave field reconstructions obtained by phase-retrieval algorithms are noisy, blurred and corrupted by various artifacts such as irregular waves, spots, etc. These distur…
