Properties of laser speckle images produced from narrow elliptical illumination regions

Abstract

The properties of laser speckles formed by laser light scattered from narrow elliptical illumination regions on a rough surface are investigated. Analytical expressions are derived for the correlation between 1D pixel data arrays in single speckle images and between averaged pixel data arrays of speckle images from different illumination regions. In deriving the formulas, the phase shift of the scattered light is expressed by a function that approximates the roughness of the illuminated surface. Experimental results are interpreted by the formulas, and the parameters of the formulas are evaluated.
