Analysis of non-Gaussian speckle by Nakagami m-distribution

The photon counting distribution of laser light scattered by a ground glass is analyzed by applying Nakagami's m -distribution to the intensity fluctuations of the speckle pattern for which the statistics are non-Gaussian. Based on the comparison of the moments between the experimental and theo...

Description
Summary:The photon counting distribution of laser light scattered by a ground glass is analyzed by applying Nakagami's m -distribution to the intensity fluctuations of the speckle pattern for which the statistics are non-Gaussian. Based on the comparison of the moments between the experimental and theoretical values, we show that the experimental data can be described by the Nakagami's m -distribution.
