TLDR
In this article, a detailed analysis of the relationship between the autocorrelation functions of clipped and unclipped photon counting fluctuations is given by evaluating the generating function for the joint distribution of intensity fluctuations, corrections to the earlier results arise if the time over which the signal is sampled is not negligible compared with any coherence time of the light.Abstract:
Digital autocorrelation of optical signals is discussed with particular reference to the technique of clipping, reported briefly in an earlier publication. A detailed analysis of the relationship between the autocorrelation functions of clipped and unclipped photon-counting fluctuations is given. By evaluating the generating function for the joint distribution of intensity fluctuations, corrections to the earlier results are calculated which arise if the time over which the signal is sampled is not negligible compared with any coherence time of the light. The effect of clipping in heterodyne experiments is also analysed.read more

The extraction of spectral parameters in photon-correlation spectroscopy
TL;DR: In this article, an analysis and discussion of the factors affecting the accuracy with which spectral parameters can be determined in photon-correlation spectroscopy on Gaussian-Lorentzian light using either direct, homodyne or heterodyne detection is presented.

Statistics of Integrated Gamma-lorentzian Intensity Fluctuations
TL;DR: In this article, the single interval statistics of an integrated gamma-distributed variable with lorentzian spectrum were derived directly from a rate equation for the process, as a special case, the integrated photon statistics predicted by a model for single-mode thermal radiation in a cavity.

Clipped correlation of integrated intensity fluctuations of gaussian light
E Jakeman,C J Oliver,E R Pike +2 more
TL;DR: In this paper, experimental confirmation of recent theoretical results of Jakeman on the time ever aging of photon-counting fluctuations when utilizing clipping techniques for autocorrelation is presented. And the effects of finite electronic resolving time (dead-time correction) and finite receiving apertures (spatial-coherence correction) are included.

Coherent and incoherent states of the radiation field
TL;DR: In this article, the photon statistics of arbitrary fields in fully quantum-mechanical terms are discussed, and a general method of representing the density operator for the field is discussed as well as a simple formulation of a superposition law for photon fields.

The spectrum of clipped noise
J. H. Van Vleck,David Middleton +1 more
TL;DR: In this paper, the authors calculate the intensity spectrum to be expected for clipped (also called "limited") noise, where the limiting amplitude is very small compared to the rms amplitude before clipping.

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.

Advances in Radar Meteorology
TL;DR: In this paper, the authors summarize significant developments in radar meteorology since 1958 and integrate them properly within the framework of knowledge existing prior to that time, and the emphasis in this chapter is on the basic principles and concepts of radar meteorologists.
