: 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 fluctuation autocorrelation of the signals generated by a conventional computational ghost imaging device. Our results illustrate how conventional computational ghost imaging without structural changes can be used to produce turbulence-free…

Turbulence-free ghost imaging

Atmospheric turbulence is a serious problem for satellite and aircraft-to-ground based classical imaging. Taking advantage of the natural, nonfactorizable, point-to-point correlation of thermal

Adaptive optical ghost imaging through atmospheric turbulence.

We demonstrate for the first time (to our knowledge) that a high-quality image can still be obtained in atmospheric turbulence by applying adaptive optical ghost imaging (AOGI) system even when

Ghost imaging through turbulent atmosphere.

TLDR
Based on the extended Huygens-Fresnel integral, an analytical imaging formula is obtained that can be viewed as the convolution of the original object and a point-spread function (PSF).

The Physics of Turbulence-Free Ghost Imaging

Since its first experimental demonstration, ghost imaging has attracted a great deal of attention due to interests in its fundamental nature and its potential applications. In terms of applications,

Positive-negative turbulence-free ghost imaging

This experiment observed turbulence-free positive and negative thermal light ghost images from independently recorded event histories of a “bucket” photo-detector and a charged coupled device (CCD)

Ghost imaging with a single detector

We experimentally demonstrate pseudothermal ghost imaging and ghost diffraction using only a single detector. We achieve this by replacing the high-resolution detector of the reference beam with a

Can a conventional optical camera realize turbulence-free imaging?

Atmospheric turbulence is a serious problem for traditional optical imaging, especially for satellite and aircraft-to-ground imaging. Here, we report a novel and practical phenomenon in which

Comment on "Turbulence-free ghost imaging" [Appl. Phys. Lett. 98, 111115 (2011)]

It is shown that lensless pseudothermal ghost imaging is not immune to spatial resolution loss from the presence of atmospheric turbulence along the propagation paths.

Turbulence-immune computational ghost imaging based on a multi-scalegenerative adversarial network

There is a consensus that turbulence-free images cannot be obtained by conventional computational ghost imaging (CGI) because the CGI is only a classic simulation, which does not satisfy the

Computational ghost imaging versus imaging laser radar for three-dimensional imaging

Ghost imaging has been receiving increasing interest for possible use as a remote-sensing system. There has been little comparison, however, between ghost imaging and the imaging laser radars with
