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…
Hybrid Diffractive Optics Design via Hardware-in-the-Loop Methodology for Achromatic Extended-Depth-of-Field Imaging
Samuel Pinilla, Seyyed Reza Miri Rostami, Igor Shevkunov +2
End-to-end optimization of diffractive optical elements (DOEs) profile through a digital differentiable model combined with computational imaging have gained an increasing attentio…
Unfolding-Aided Bootstrapped Phase Retrieval in Optical Imaging
Samuel Pinilla, Kumar Vijay Mishra, Igor Shevkunov +3
Phase retrieval in optical imaging refers to the recovery of a complex signal from phaseless data acquired in the form of its diffraction patterns. These patterns are acquired thro…
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…
ADMM and Spectral Proximity Operators in Hyperspectral Broadband Phase Retrieval for Quantitative Phase Imaging
Vladimir Katkovnik, Igor Shevkunov, Karen Egiazarian
A novel formulation of the hyperspectral broadband phase retrieval is developed for the scenario where both object and modulation phase masks are spectrally varying. The proposed a…
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…
