Reconstruction of a stable and reliable solution from noisy and incomplete Fourier intensity data is a challenging problem for iterative phase retrieval algorithms. The typical methodology employed in the coherent X-ray imaging (CXI) literature involves thousands of iterations of well-known phase retrieval algorithms, e.g., hybrid input-output (HIO) or relaxed averaged alternating reflections (RAAR), that are concluded with a smaller number of error reduction (ER) iterations. Since the single…

Complexity-guided Fourier phase retrieval from noisy data.

The proposed strategy for controlling the solution complexity within and outside the support during the HIO iterations is proposed and tested and observes that the performance of the proposed strategy is noise robust in the sense that with increasing noise, the quality of the phase solution degrades gradually.

Oversampling smoothness: an effective algorithm for phase retrieval of noisy diffraction intensities.

Both numerical simulations with Poisson noise and experimental data from a biological cell indicate that OSS consistently outperforms the HIO, ER-HIO and noise robust (NR)-HIO algorithms at all noise levels in terms of accuracy and consistency of the reconstructions.

Phase retrieval with complexity guidance.

A modified Fienup algorithm that uses a controlled sparsity-enhancing step such that in every iteration the complexity of the resulting guess solution is explicitly made close to ζ is proposed, which is seen to provide an artifact-free phase retrieval solution within a few hundred iterations.

Hybrid projection-reflection method for phase retrieval.

A new projection-based method, termed the hybrid projection-reflection (HPR) algorithm, is introduced for solving phase-retrieval problems featuring nonnegativity constraints in the object domain, motivated by properties of the HPR algorithm for convex constraints.

Phase retrieval algorithms: a comparison.

Iterative algorithms for phase retrieval from intensity data are compared to gradient search methods and it is shown that both the error-reduction algorithm for the problem of a single intensity measurement and the Gerchberg-Saxton algorithm forThe problem of two intensity measurements converge.

A generalization for optimized phase retrieval algorithms.

By introducing additional operations inside the support term of existing iterated projection algorithms, this work demonstrates an improved method for iterative phase retrieval with application to coherent diffractive imaging and offers a new array of methods for efficiently deconvolving intricate data.

Random projections and the optimization of an algorithm for phase retrieval

Iterative phase retrieval algorithms typically employ projections onto constraint subspaces to recover the unknown phases in the Fourier transform of an image, or, in the case of x-ray

Several strategies in phase retrieval are unified by an iterative "difference map" constructed from a pair of elementary projections and three real parameters, which illuminates the distinction between its fixed points and the recovered object.

Phase retrieval, error reduction algorithm, and Fienup variants: a view from convex optimization.

A theoretical framework is provided to better understand and to improve existing phase recovery algorithms and to establish new connections between well-established numerical phase retrieval schemes and classical convex optimization methods.

Hawk: the image reconstruction package for coherent X‐ray diffractive imaging

The past few years have seen a tremendous growth in the field of coherent X-ray diffractive imaging, in large part due to X-ray free-electron lasers which provide a peak brilliance billions of times
