Abstract

Speckle correlation is one of the most important characteristics
of the speckle pattern for various practical applications. It is a
second order statistics of a random variable describing how far
is crowded the roughness of the surface material and its slope
of curvature. Speckle correlation function arises from the
convolution of spatial distribution of a diffraction pattern due
.~
to the imaging system and the interference pattern of scattered
waves from a rough surface. The present thesis gives more
attention on the effect of the illuminating imaging aperture on
. the speckle correlation. The effect of the surface roughness
characteristics, from a simple theoretical point of view, is also
studied.
The Chapters of the thesis are structured as follows:
Chapter 1 gives some information on the criterion of arising
speckle pattern. The characteristics of speckle contrast, speckle
correlation and previous work are presented.
Chapter 2 gives a brief analytical study of Fresnel integral of
diffraction. It also introduces a study on the spatial distribution
of a diffraction pattern ansmg from some illuminating
