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 …

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 …

By measuring a linear response function directly, such as the dynamic susceptibility, one
can understand fundamental material properties. However, a fresh perspective can be …

Wavefront sensing is an essential tool in wide research areas. However, the auxiliary
reference beam and the pixel-array detector are indispensable in most of the wavefront …

Conventional coherent diffraction imaging (CDI) suffers from inherent phase retrieval
ambiguity due to limited intensity-only measurements. Coded illumination with multiple …

The realm of classical phase retrieval concerns itself with the arduous task of recovering a
signal from its Fourier transform magnitude, which is fraught with inherent ambiguities. A …

We describe, through simulations and experiments, a real-time wavefront acquisition
technique using random binary amplitude masks and an iterative phase retrieval algorithm …

A single-shot phase retrieval algorithm based on a random aperture and partially saturated
diffraction pattern is proposed. The diffraction pattern in the saturated area could be …

Multiple distance phase retrieval is a technique of using a series of intensity patterns to
reconstruct a complex-valued image of object. However, tilt illumination originating from the …
