TLDR
This work reports coherent imaging of objects behind opaque scattering media with only one piece of the Fourier transform power spectrum pattern under coherent illumination, which extends the methodology of x-ray crystallography to visible-light scattering imaging for underwater and living biomedical imaging.Abstract:
We report coherent imaging of objects behind opaque scattering media with only one piece of the power spectrum pattern. We solve the unique solution and improve algorithm speed for the inverse problem. Based on the proposed scattering-disturbance model, with only one piece of the Fourier transform power spectrum pattern under coherent illumination, we successfully reconstruct clear images of the objects fully hidden by an opaque diffuser. The experimental results demonstrate the feasibility of the reconstruction method and the scattering-disturbance model. Our method makes it possible to carry out snapshot coherent imaging of the objects obscured by scattering media, which extends the methodology of x-ray crystallography to visible-light scattering imaging for underwater and living biomedical imaging.read more

Phase extraction neural network (PhENN) with coherent modulation imaging (CMI) for phase retrieval at low photon counts
TL;DR: It is demonstrated that random phase modulation on the optical field, also known as coherent modulation imaging (CMI), in conjunction with the phase extraction neural network (PhENN) and a Gerchberg-Saxton-Fienup (GSF) approximant, further improves resilience to noise of the phase-from-intensity imaging problem.

TL;DR: In this paper, disordered media made of randomly distributed nanoparticles can be used to overcome the diffraction limit of a conventional imaging system, and a method to extract the original image information from the multiple scattering induced by the turbid media is proposed.

Harnessing disorder for photonic device applications
Hui Cao,Yaniv Eliezer +1 more
TL;DR: For photonic devices, structural disorder and light scattering have long been considered annoying and detrimental features that were best avoided or minimized as discussed by the authors , but structural disorder can be harnessed for photonic device applications.

Wavelength-dependent speckle multiplexing for imaging through opacity
Rui Ma,Zhao Wang,Wen Yu Wang,Yong Zhang,Jun Liu,Weili Zhang,Anderson S. L. Gomes,Dian Yuan Fan +7 more
TL;DR: In this paper, the wavelength-dependent speckle multiplexing (WDSM) technique is proposed and demonstrated as an effective method to suppress the interference noise, thereby facilitating the use of partially spatially coherent light as an alternative promising illuminating source.

Single-frame far-field diffractive imaging with randomized illumination.
TL;DR: RPI offers an attractive modality for quantitative X-ray phase imaging when temporal resolution and reliability are critical but spatial resolution in the tens of nanometers is sufficient.

Image transmission through an opaque material.
TL;DR: 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.
