Computational methods have been established as cornerstones in optical imaging and
holography in recent years. Every year, the dependence of optical imaging and holography …

Off-axis holographic multiplexing involves capturing several complex wavefronts, each
encoded into off-axis holograms with different interference fringe orientations …

Phase retrieval, ie the problem of recovering a function from the squared magnitude of its
Fourier transform, arises in many applications, such as X-ray crystallography, diffraction …

A non-iterative and non-interferometric computational imaging method to reconstruct a
complex wave field called synthetic aperture imaging based on Kramers–Kronig relations …

Given the low absorption contrast of X-rays, phase shift has been playing an important role
as an alternative source of contrast in X-ray nanoimaging. Numerous phase-measuring …

Zero-order and twin images are a serious obstacle in achieving a high-quality output in in-
line digital holography (DH). They decrease the useful bandwidth of the off-axis DH. Over …

We address the problem of reconstructing a sparse signal from its DFT magnitude. We refer
to this problem as the sparse phase retrieval (SPR) problem, which finds applications in …

Abstract Optical Metasurfaces (MSs), a new class of planar optical elements, are profoundly
disrupting the field of optical design, notably due to their compactness, multi-functionalities …

We address the problem of phase retrieval from Fourier transform magnitude spectrum for
continuous-time signals that lie in a shift-invariant space spanned by integer shifts of a …

Single-frame off-axis holographic reconstruction is promising for quantitative phase imaging.
However, reconstruction accuracy and contrast are degraded by noise, frequency spectrum …
