When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

Accurate depiction of waves in temporal and spatial is essential to the investigation of
interactions between physical objects and waves. Digital holography (DH) can perform …

Ptychographic Coherent Diffractive Imaging enables diffraction-limited imaging of nanoscale
structures at extreme ultraviolet and x-ray wavelengths, where high-quality image-forming …

Phase retrieval is a long-standing problem in imaging when only the intensity of the
wavefield can be recorded. Coherent diffraction imaging is a lensless technique that uses …

Ever brighter light sources, fast parallel detectors and advances in phase retrieval methods
have made ptychography a practical and popular imaging technique. Compared to previous …

Ptychography is a form of scanning diffractive imaging that can successfully retrieve the
modulus and phase of both the sample transmission function and the illuminating probe. An …

Two modified Gerchberg–Saxton (GS) iterative phase retrieval algorithms are proposed. The
first we refer to as the spatial phase perturbation GS algorithm (SPP GSA). The second is a …

We present a method of quantitatively acquiring a large complex field, containing not only
amplitude information but also phase information, based on single-shot phase imaging with …

We study the Kaczmarz methods for solving systems of phaseless equations, ie, the
generalized phase retrieval problem. The methods extend the Kaczmarz methods for solving …

We demonstrate necessary and sufficient conditions of the local convergence of the
alternating projection algorithm to a unique solution up to a global phase factor. Additionally …
