In this paper we analyze an imaging technique based on intensity speckle correlations over incident field position proposed by Newmann and Webb (2014 Phys. Rev. Lett. 113 263903). Its purpose is to reconstruct a field incident on a strongly scattering random medium. The thickness of the complex medium is much larger than the scattering mean free path so that the wave emerging from the random section forms an incoherent speckle pattern. Our analysis clarifies the conditions under which the… 
Enhanced Backscattering of a partially coherent field from an anisotropic random lossy medium
The weak localization or enhanced backscattering phenomenon has received a lot of attention in the literature. The enhanced backscattering cone refers to the situation that the wave backscattered by
Speckle Memory Effect in the Frequency Domain and Stability in Time-Reversal Experiments
When waves propagate through a complex medium like the turbulent atmosphere the wave field becomes incoherent and the wave intensity forms a complex speckle pattern. In this paper we study a speckle
Scintillation of Partially Coherent Light in Time Varying Complex Media
We present a theory for wave scintillation in the situation with a timedependent partially coherent source and a time-dependent randomly heterogeneous medium. Our objective is to understand how the
Inverse wave propagation problems without phase information
This special issue captures recent developments in the classical phase problem in quantum mechanics, optics, and related areas. In particular, Born’s rule in quantum mechanics from 1926, for which he


Imaging optical fields through heavily scattering media.
A remarkable result based on speckle correlations over incident field position is reported that demonstrates that the field incident on a heavily scattering random medium can be obtained using a method that is not restricted to weak scatter and is, in principle, independent of the thickness of the scattering medium.
Imaging Hidden Objects with Spatial Speckle Intensity Correlations over Object Position.
Spatial speckle intensity correlations as a function of object position are shown to provide access to the spatially dependent dielectric constant of the moving object, which yields field-based information previously inaccessible in heavily scattering environments.
Fourier magnitude of the field incident on a random scattering medium from spatial speckle intensity correlations.
Spatial speckle intensity correlations are used to determine the spatial Fourier magnitude of a field incident on a random scattering medium. The patterned beam is scanned across the scattering
Random matrix theory applied to acoustic backscattering and imaging in complex media.
The singular values distribution of the propagation operator in a random medium is investigated in a backscattering configuration and an experimental illustration of imaging through a highly scattering slab is presented.
Image transmission through an opaque material.
This work shows that it is possible to measure the complex mesoscopic optical transmission channels that allow light to traverse through such an opaque medium and optimally exploit those channels to coherently transmit and recover an arbitrary image with a high fidelity, independently of the complexity of the propagation.
Enhanced statistical stability in coherent interferometric imaging
We analyze the resolution and statistical fluctuations of images when the ambient medium is random and scattering can be modeled primarily by wavefront distortion. We compare the coherent
A random matrix approach to detect defects in a strongly scattering polycrystal: How the memory effect can help overcome multiple scattering
We report on ultrasonic imaging in a random heterogeneous medium. The goal is to detect flaws embedded deeply into a polycrystalline material. A 64-element array of piezoelectric
Exploiting disorder for perfect focusing
Optical microscopy and manipulation methods rely on the ability to focus light to a small volume. However, in inhomogeneous media such as biological tissue, light is scattered out of the focusing
Coupled paraxial wave equations in random media in the white-noise regime
In this paper the reflection and transmission of waves by a three-dimensional random medium are studied in a white-noise and paraxial regime. The limit system derives from the acoustic wave equations
