Phase retrieval with random phase illumination [PDF]

open access: yesJournal of the Optical Society of America A, 2012
This paper presents a detailed, numerical study on the performance of the standard phasing algorithms with random phase illumination (RPI). Phasing with high resolution RPI and the oversampling ratio $σ=4$ determines a unique phasing solution up to a global phase factor. Under this condition, the standard phasing algorithms converge rapidly to the true

On stability of generalized phase retrieval and generalized affine phase retrieval

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we consider the stability of intensity measurement mappings corresponding to generalized phase retrieval and generalized affine phase retrieval in the real case. First, we show the bi-Lipschitz property on measurements of noiseless signals.

Reconstruction of Isolated Moving Objects by Motion-Induced Phase Shift Based on PSP

open access: yesApplied Sciences, 2021
The reconstruction of moving objects based on phase shifting profilometry has attracted intensive interests. Most of the methods introduce the phase shift by projecting multiple fringe patterns, which is undesirable in moving object reconstruction as the

Generalized Phase (Norm) Retrieval Hermitian Matrices and $G$-frames [PDF]

open access: yesSahand Communications in Mathematical Analysis
This paper is an analysis of the generalized phase (norm) retrieval problem, which aims to reconstruct a signal from its quadratic measurements. We provide some connections between phase (norm) retrieval $G$-frames and generalized phase (norm) retrieval ...

Solving multiple windowed STFT phase retrieval problems in phase and amplitude respectively

open access: yesApplied Mathematics in Science and Engineering, 2022
We study the Phase Retrieval (PR) problem under the phaseless short-time Fourier transform (STFT) measurements. This paper proposes a novel algorithm named PAR to solve the STFT PR problem in phase and amplitude respectively with a milder retrieval ...

PhasePack: A phase retrieval library [PDF]

open access: yes2017 51st Asilomar Conference on Signals, Systems, and Computers, 2017
Phase retrieval deals with the estimation of complex-valued signals solely from the magnitudes of linear measurements. While there has been a recent explosion in the development of phase retrieval algorithms, the lack of a common interface has made it difficult to compare new methods against the state-of-the-art. The purpose of PhasePack is to create a
