Temporal ghost imaging with pseudo-thermal speckle light
We report ghost imaging of a single non-reproducible temporal signal with kHz resolution by using pseudo-thermal speckle light patterns and a single detector array with a million of pixels working without any temporal resolution. A set of speckle patterns is generated deterministically at a sampling rate of tens kHz, multiplied by the temporal signal and time integrated in a single shot by the ...
متن کاملGhost Imaging without Discord
Ragy and Adesso argue that quantum discord is involved in the formation of a pseudothermal ghost image. We show that quantum discord plays no role in spatial light modulator ghost imaging, i.e., ghost-image formation based on structured illumination realized with laser light that has undergone spatial light modulation by the output from a pseudorandom number generator. Our analysis thus casts d...
متن کاملNormalized ghost imaging
We present an experimental comparison between different iterative ghost imaging algorithms. Our experimental setup utilizes a spatial light modulator for generating known random light fields to illuminate a partially-transmissive object. We adapt the weighting factor used in the traditional ghost imaging algorithm to account for changes in the efficiency of the generated light field. We show th...

متن کاملGhost Imaging with X Rays
C onventional imaging methods capture an image of an object by recording, in a multipixel detector, the intensity and color of a light beam that hits the object. The technique of ghost imaging is different. It forms an image of the object using correlations between the intensities of two light beams, an “object beam” that strikes the object and a “reference beam” that does not. Crucially, in th...
