The study of optical statistical properties and coherence for XFEL
14th National Conference on Laser Technology and Optoelectronics (LTO 2019), 2019A X-ray free-electron laser (XFEL) facility is based on RF superconducting accelerator at China Academy of Engineering Physics (CAEP) has been planed. The facility will be designed in a radiation range of 0.3-4 angstrom and the electron beam energy will be 12GeV.

Optical-coherence tomography of a dense tissue: statistics of attenuation and backscattering
Physics in Medicine and Biology, 1994This paper addresses fundamental issues that underlie the interpretation of images acquired from turbid tissues by optical-coherence tomography (OCT). The attenuation and backscattering properties of freshly excised rat arteries and their dependence on the focusing and collection optics of the OCT system were measured at two wavelengths in the near ...

Even and odd q-coherent states and their optical statistics properties
Journal of Physics A: Mathematical and General, 1993Summary: We construct explicitly even and odd \(q\)-coherent states \((qCSs)\), which are proved to form a representation of the quantum Heisenberg-Weyl algebra, and study their properties. It is shown that optical statistics properties of the even and odd \(qCSs\) are very different.

A statistical model of retinal optical coherence tomography image data
2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011Optical coherence tomography (OCT) is an important mode of biomedical imaging for the diagnosis and management of ocular disease. Here we report on the construction of a synthetic retinal OCT image data set that may be used for quantitative analysis of image processing methods.

Optical statistical classifiers using coherent and incoherent light
Applied Optics, 1979Breast thermograms are digitally classified by means of a principal component analysis of a training set of breast spectral differences obtained in coherent light. The results are compared to the usual partition in categories of medical diagnosis. The statistical operators initiating the classification being expressed in terms of spatial frequencies ...

Statistical properties of coherent radiation in a nonlinear optical amplifier
Physical Review A, 1980The differential equation for the photon conditional probability distribution in a nonlinear amplifier is numerically solved, using the continuous approximation. Saturation effects on the development of fluctuations in the amplification of coherent light are studied. They are compared with the results obtained by solving the moment equations.

Role of Statistics of Primary Excitations in Optical Coherence
1984We examine the coherence properties of stationary light obtained by the superposition of nonstationary emissions, occurring at random space-time points. The positions of the points are uniformly distributed over the volume of the source. The emission times fluctuate in accordance with a stationary renewal point process.

Statistics of the depth-scan photocurrent in time-domain optical coherence tomography
Journal of the Optical Society of America A, 2007We derive the time-variant second-order statistics of the depth-scan photocurrent in time-domain optical coherence tomography (TD-OCT) systems using polarized thermal light sources and superluminescent diodes (SLDs). Since the asymptotic-joint-probability-distribution function (JPDF) of the photocurrent due to polarized thermal light is Gaussian and ...

Influence of coherent properties of an optical field on the photocount statistics
Soviet Journal of Quantum Electronics, 1985The asymmetry of photocount statistics in respect of the spatial and temporal coherence factors is demonstrated and explained. This asymmetry appears because of the "dead time" of a counter receiving a non-Poisson photoelectron flux. A statistical model of an optical field, photoelectron flux, and counting flux is used in a computer study of the ...

Statistical model for free-space optical coherent communications using adaptive optics
SPIE Proceedings, 2016In this paper we present a new model for describing the turbulence-induced fading that uses the representation of the phase in the aperture plane as a collection of random “cells”. This model serves as input to calculate the probability density function of fading intensity. The model has two parameters: phase variance and number of wavefront cells . We
