Second-order statistics of non-Gaussian fluctuations of coherent waves reflected from disordered media.
We show that the second-order statistics of speckle patterns of scalar waves, multiply scattered on reAection by disordered media, may be non-Gaussian, even though the first-order statistics are Gaussian. This occurs at intermediate sizes of the illuminated samples of the medium that are large enough to produce Gaussian first-order statistics of the scattered field but are small enough to break...
متن کاملEnhanced long-range correlations of coherent waves reflected from disordered media.
We study the intensity angular correlation function of scalar waves, scattered on reAection from disordered media, for the case in which the sample is so small that the speckle pattern does not follow a joint Gaussian statistics, and thus the factorization approximation does not hold. An enhanced long-range correlation is predicted that exhibits two peaks due to coherent effects analogous to th...
متن کاملPosition Detection Based on Intensities of Reflected Infrared Light
This thesis focus on development of methods for using infrared sensors for position detection. There exists various methods where optical sensors are used to give position estimates, many utilizing multiple cameras. The overall approach in this thesis is to base a position detection sensor system on inputs from an array of infrared emitters and receivers. The signals from the emitters are refle...
متن کاملPeople counter based on fusion of reflected light intensities from an infrared sensor array
An effective low-cost solution to determine characteristic features of objects from a simple infrared diode array, working on the reflection light scanner principle and using the fusion of amplitude information to detect and characterize objects, has been designed. Essentially, two arrays of several emitter-receiver pairs are mounted on opposite sides of the area of observation (e.g. a conveyer...
متن کاملViscosity in disordered media
The paper addresses the properties of glassforming melts in an attempt to predict the dependence of viscosity on temperature and on pressure. A review on the main viscosity models (free volume model, the Adam and Gibbs model etc.) is given. It is demonstrated that the activation energy can be expressed through the glass-transition temperature Tg. The main attention is concentrated on the jump f...
