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…
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…
