Turbulence-free computational ghost imaging
Turbulence-free images cannot be produced by conventional computational ghost imaging because calculated light is not affected by the same atmospheric turbulence as real light. In this article, we first addressed this issue by measuring the photon number

Multi-wavelength compressive computational ghost imaging
The field of ghost imaging encompasses systems which can retrieve the spatial information of an object through correlated measurements of a projected light field, having spatial resolution, and the associated reected or trans-mitted light intensity ...

Circuit-Based Modular Implementation of Quantum Ghost Imaging
Although promising in terms of its applications in many facets of science and engineering; notably, in laser technology and remote sensing, ghost imaging is primarily impeded by its intense demands related to computational overhead, which impacts on the ...

Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media. [PDF]
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Temporal Ghost Imaging by Means of Fourier Spectrum Acquisition
Ghost imaging is a fascinating framework which constructs the image of an object by correlating measurements between received beams and reference beams, none of which carries the structure information of the object independently. Recently, by taking into
