A Recovery Method of Double Random Phase Encoding System With a Parallel Phase Retrieval
IEEE Photonics Journal, 2016 A novel method composed of phase retrieval is proposed to precisely recover the phase distribution in the double random phase encoding system. The model of a point light source is employed to illuminate the system, in the output side of which several ...

Undersampled Phase Retrieval with Outliers [PDF]
, 2014 We propose a general framework for reconstructing transform-sparse images from undersampled (squared)-magnitude data corrupted with outliers. This framework is implemented using a multi-layered approach, combining multiple initializations (to address the

Retrieval-Induced Forgetting in a Pentylenetetrazole-Induced Epilepsy Model in the Rat
Brain Sciences, 2018 The selective retrieval of some information may lead to the forgetting of related, but non-retrieved information. This memory phenomenon is termed retrieval-induced forgetting (RIF).

Enhanced Phase Retrieval Method Based on Random Phase Modulation
Applied Sciences, 2020 The phase retrieval method based on random phase modulation can wipe out any ambiguity and stagnation problem in reconstruction. However, the two existing reconstruction algorithms for the random phase modulation method are suffering from problems.

Under-Sampled Phase Retrieval of Single Interference Fringe Based on Hilbert Transform
IEEE Access, 2019 Phase retrieval from single interference fringe is important and effective method in obtaining the real phase distribution. The original phase can be retrieved by the line integral of its gradient expressed as sine and cosine components, which were ...

Modified Gerchberg–Saxton (G-S) Algorithm and Its Application
Entropy, 2020 The Gerchberg–Saxton (G-S) algorithm is a phase retrieval algorithm that is widely used in beam shaping and optical information processing. However, the G-S algorithm has difficulty obtaining the exact solution after iterating, and an approximate ...

Solving systems of phaseless equations via Kaczmarz methods: A proof of concept study [PDF]
, 2015 We study the Kaczmarz methods for solving systems of quadratic equations, i.e., the generalized phase retrieval problem. The methods extend the Kaczmarz methods for solving systems of linear equations by integrating a phase selection heuristic in each ...

Phase retrieval by hyperplanes
, 2017 We show that a scalable frame does phase retrieval if and only if the hyperplanes of its orthogonal complements do phase retrieval. We then show this result fails in general by giving an example of a frame for $\mathbb R^3$ which does phase retrieval but
