Holographic phase retrieval

In this chapter we will first introduce holograp hic based methods, or the digital holography approach, as a solution to the phase retrieval problem. These methods use an optical setup, Holograms computed using our "learned hardware-in-the-loop phase retrieval" eliminates severe aberrations and show an improved quality, enhanced resolution and remarkable contrast, with black regions truly being black as shown below. We achieve all of this in a holographic display, perhaps for the first time to the best of our knowledge. 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 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 images and .

These methods use an optical setup, A general mathematical framework and recovery algorithm is presented for the holographic phase retrieval problem. In this problem, which arises in holographic 2013-05-31 · Inline holography is a common phase-contrast imaging method which uses free-space propagation to encode the phase signal into measured intensities. However, quantitative retrieval of the sample's The phase-retrieval algorithms represent the core of the toolbox and are grouped into two major classes, one for the direct-contrast regime and the other for the holographic regime. Depending on the problem and particular algorithm, phase retrieval can be performed with or without the different approximations (weak object) and constraints (pure phase or range constraints, single-material and support constraints).

However, recovering the phase properties of an object in a holo-gram needs an object plane to be chosen correctly for reconstruction. In this work, we present a novel CONFERENCE PROCEEDINGS Papers Presentations Journals. Advanced Photonics Journal of Applied Remote Sensing Learned hardware-in-the-loop phase retrieval for holographic near-eye displays Praneeth Chakravarthula, Ethan Tseng, Tarun Srivastava, Henry Fuchs, Felix Heide Computer Science We present an iterative phase retrieval algorithm that allows the projection of amplitude-controlled speckle-free one-dimensional patterns with a high degree of pattern uniformity. The algorithm, termed the weighted Gerchberg–Saxton with phase-control (GSW-PC), is shown to have the ability to simultaneously control both the phase and amplitude of projected patterns with high diffraction The resulting inverse problem, known as holographic phase retrieval, Keywords: inverse problems, phase retrieval, generative priors, holography, coherent (2020) tested the deep decoder, both untrained neural networks, for Fourier phase retrieval, but did not consider the holographic setting.

1972. 2017-02-28 · Compared to traditional phase retrieval approaches, our SPR algorithm uses over an order of magnitude less pixel measurements while maintaining suitable reconstruction quality. We use an on-chip holographic video setup with pixel sub-sampling to experimentally demonstrate a factor of 5.5 increase in sensor frame rate while monitoring the in vivo movement of Peranema microorganisms.
