Image-plane speckle in partially coherent illumination
TL;DR: In this article, the first and second order statistical properties of speckle formed in the image of a diffuse object when the illumination is both temporally and spatially partially coherent are derived.

Surface roughness measurements by means of speckle wavelength decorrelation
M. Giglio,S. Musazzi,U. Perini +2 more
TL;DR: In this paper, the authors exploit speckle wavelength decorrelation techniques for the characterization of surface roughness up to a few microns, using an argon laser, a grating, two photodetectors, and a commercial cross correlator.

Spectral and temporal speckle field measurements of a random medium.
TL;DR: The zero-mean circular complex Gaussian field statistics of a random medium are experimentally demonstrated in the optical domain, thus verifying this key assumption of statistical optics.

SNR in photocounting images of rough objects in partially coherent light
Marek Elbaum,Paul Diament +1 more
TL;DR: The expression for the SNR at the detector output is obtained as a function of the coherence of the illuminating light, the object surface roughness, the width of the telescope point spread function, and the aperture and integration time of the detector.

On a moment theorem for complex Gaussian processes
TL;DR: A general theorem is provided for the moments of a complex Gaussian video process that states that an n th order central product moment is zero if n is odd and is equal to a sum of products of covariances when n is even.

Fluctuations of Photon Beams: The Distribution of the Photo-Electrons
TL;DR: In this article, the probability distribution p(n, T) of the number of counts n from a photoelectric detector illuminated by coherent light for a time T is studied, by associating photons stochastically with Gaussian random waves.

Some effects of target-induced scintillation on optical radar performance
TL;DR: In this paper, the statistical performance of pulsed optical radars that use energy detection is considered, and the physical factors influencing the number of observed correlation cells for the cases of partial and total interception of the transmitted beam are examined.
