In this problem, which arises in holographic coherent diffraction imaging, a "reference" portion of the signal to be recovered via phase retrieval is a priori known from experimental design. A general mathematical framework and recovery algorithm is presented for the holographic phase retrieval problem. In this problem, which arises in holographic In the computational imaging community, many attempts have been made in solving holographic phase retrieval using references, among which has been very successful. Motivated by the reference design for holographic phase retrieval, we are trying to explore a way to design references for general phase retrieval.

Holographic phase retrieval

However, recovering the phase properties of an object in a hologram needs an object plane to be chosen correctly for reconstruction. In this work, we present a novel multi-wavelength Gerchberg-Saxton algorithm to determine the object plane using single-shot This article describes scientific software made publicly available for phase retrieval in X-ray propagation imaging. The package is called HoloTomoToolbox and comprises a set of algorithms for phase retrieval in the direct-contrast regime, as well as in the holographic regime, which is used for high-resolution cone-beam synchrotron recordings.

A variant of this setup, known as holography, includes a reference object that is placed adjacent to the specimen of interest before measurements are collected. by the reference design for holographic phase retrieval, we are trying to explore a way to design references for general phase retrieval. Phase Retrieval. The phase retrieval problem has drawn considerable at-tention over the years, as many optical detection devices can only measure The on-axis methods can fully utilize the space–bandwidth product of the DH system. However, to achieve high phase retrieval accuracy, phase-shifting methods must record several holograms (typically ≥3) in time sequence or in a single shot , , , .

In this problem, which arises in holographic phase retrieval is the assumption that the sample interacts sufficiently weakly with the X-rays such that the relation (1) can be linearized with respect to the phase and absorption 2021-03-07 A general mathematical framework and recovery algorithm is presented for the holographic phase retrieval problem. In this problem, which arises in holographic coherent diffraction imaging, a "reference" portion of the signal to be recovered via phase retrieval is a priori known from experimental design.

Phase retrieval and the twin-image problem in digital in-line holographic microscopy can be resolvedby iterative reconstruction routines. However, recovering the phase properties of an object in a hologramneeds an object plane to be chosen correctly for reconstruction. Pulse terahertz holography introduced some years ago shows itself as perfect method for overall-object phase retrieval technique, but in the same time it allows measurement with low signal to noise Learned Hardware-in-the-loop Phase Retrieval for Holographic Near-Eye Displays. Holographic displays often show poor image quality due to severe real world deviations in the light propagation compared to the simulated “ideal” light propagation model. We built a holographic display-camera setup (left) to generate data that is used to train a neural Dual-Reference Design for Holographic Phase Retrieval Abstract: A new reference design is introduced for holographic coherent diffraction imaging. This consists in two references-"block" and "pinhole" shaped regions-placed adjacent to the imaging specimen. Because of its simple optical system setup and robust noise tolerance, non-interferometric phase retrieval is an important technique for phase-modulated holographic data storage.

Because the reference beam should be always known both in the recording process and reading process, there is no extra material cost for saving the be explored in order for phase retrieval to advance. Relatedwork. There has been recent empirical evidence supporting applying a deep learning based approach to holographic imaging, a phase retrieval problem.
