Benefiting from the memory effect (ME) for speckle intensity correlations, only one single-shot speckle pattern can be used for the high-quality recovery of objects. However, ME gives a restriction to the field of view (FOV) for imaging with scattering media. Objects beyond the ME region cannot be recovered and produce unwanted speckle patterns, which cause reduction in the speckle contrast and recovery quality. Nevertheless, all the spatial information from a large object is embedded in a… Expand

Color imaging through a scattering layer from one grayscale speckle pattern
TLDR

Imaging through scattering layers exceeding memory effect range by exploiting prior information
TLDR
This work experimentally demonstrates that given a known target, or even a light point-source, the other unknown object beyond the ME can be determined with only a single-shot camera image, even if the information of targets are mixed in the speckle pattern. Expand
Single-shot multi-view imaging enabled by scattering lens.
TLDR
It is demonstrated that both stereo imaging with large disparity and up to seven-view imaging of a 3D object can be reconstructed from only one speckle pattern by deconvolution by utilizing the memory effect and uncorrelated point spread functions among scattering media. Expand

A new method to reconstruct the speckle image using the original image information obtained by one-time detection, where the autocorrelation of the object with the highest reflectivity is filtered by peak searching, and reconstructed by phase retrieval. Expand

Imaging moving targets through scattering media.
TLDR
This work demonstrates the ability to image hidden, moving objects in a bright-field scenario by using a deterministic phase modulator to generate a spatially incoherent light source, and shows that the background contribution can be kept constant between acquisitions and subtracted out. Expand
Single-shot diffraction-limited imaging through scattering layers via bispectrum analysis.
TLDR
It is experimentally demonstrated that in addition to Fourier amplitude, the object-phase information is naturally and inherently encoded in the scattered light bispectrum (the Fourier transform of triple correlation) and can also be extracted from a single high-resolution speckle pattern. Expand

TLDR
The realization of high speed color imaging through turbid media is successfully carried out by taking into account the media memory effect, the point spread function, the exit pupil of the optical system, and the optimized signal to noise ratio. Expand
