Physical Review A

Onefold photoelectron counting statistics for non-Gaussian light: Scattering from polydispersive suspensions

Richard G. Barakat, Julian Blake

Abstract

Onefold photoelectron counting distributions are evaluated for coherent light scattered by an ensemble of particles. The ensemble contains, in general, a random number of nonidentical particles. Expressions are obtained for the probability density function and the moments of the scattering intensity. These results reduce to those of Pusey, Schaefer, and Koppel when the particles are identical. Photocount probabilities are also evaluated. The variance, coefficient of skewness, and coefficient of excess are evaluated when the probability density of the intensity contributed by each scatterer is specified by a narrow Gaussian distribution centered about the deterministic mean.

Onefold photoelectron-counting statistics for non-Gaussian light: scattering from an arbitrary number of weak scatterers

Richard G. Barakat

The onefold photoelectron-counting statistics (e.g., probability distribution and moments) are obtained when the physical system under study contains an arbitrary number of independent weak (i.e., nonuniform phase) scatterers. The results are generalized by letting the number of scatterers be random and be governed by a Poisson distribution.

Generating Function of the N-fold Photoelectric Counting Distribution for Gaussian Light

Cyrus D. Cantrell

An exact expression is obtained for the generating function of the N-fold (i.e., N-detector) photoelectron counting distribution for cross-spectrally pure Gaussian light, in terms of the onefold generating function. It is assumed that the counting times at the different detectors are all equal, but not necessarily short compared to the coherence time of the light. In cases where the onefold generating function can be calculated, a closed formula for the N-fold generating function can be obtained.

Single-interval statistics of light scattered by identical independent scatterers

P. N. Pusey, Dale W. Schaefer, D E Koppel

The authors consider the statistical properties of coherent light Rayleigh-scattered by a solution containing an arbitrary number N of independent, identical particles. Expressions are obtained for the single-interval intensity probability distribution and the moments of this distribution, which are equivalent to the measurable photocount factorial moments.

Onefold photoelectron-counting statistics of mixtures of thermal and coherent radiation

Richard G. Barakat

We consider onefold photoelectron-counting statistics, for arbitrary counting times, when the wave field on the detector is a mixture of thermal light of a specified spectral profile (incoherent component) and a harmonic signal (coherent component). The probability density function of the time-integrated intensity W(Ω) is obtained from the inverse Laplace transform of the moment-generating function by the Dubner–Abate algorithm. The corresponding probability distribution of the detected photoelectrons, P(m), is then evaluated directly by numerical integration of W(Ω). Numerical results for W(Ω) and P(m) have been obtained when the thermal line shape is Lorentzian for both the homodyne situation (coherent line coincides with the mean frequency of the thermal spectral profile) and the heterodyne situation (coherent line is now off center with respect to the mean frequency of the thermal spectral profile).

Photoelectron Counting Statistics of Laser Light Scattered by Very Dilute Solution

Manabu Yoshikawa, Norihito Suzuki, Tatsuro Suzuki

The photon counting statistics of light is studied, in which the various types of photon counting distribution can be represented by Nakagami'sm-distribution. To investigate this theoretical utility we have measured the photon counting distribution of laser light scattered by a very dilute solution in which non-Gaussian statistics appear. The comparison is also made by the factrial moment between the experimental value and theoretical one. The experimental distribution is in agreement with the theoretical distribution.

Photon Counting and Intensity Fluctuations of Partially Polarized Gaussian Light

A. K. Jaiswal, C. L. Mehta

We study the photocounting statistics and the integrated intensity distribution of partially polarized Gaussian light. Expressions for the characteristic functions of the two distributions are obtained in terms of the eigenvalues of an associated integral equation. Closed-form expressions for these characteristic functions are derived for the special case when the spectral profile of the light is Lorentzian. Results from a numerical evaluation of the factorial moments of the number of photoelectrons in a given time interval and of the integrated intensity distribution are also presented.
