Paper Abstract

Experimental results are presented for the angular correlation function of far field speckle patterns scattered in the double passage of waves through a one-dimensional random phase screen. The experiment for the correlation measurement was set up to use a CCD camera to obtain the image of the speckle patterns in the scattering directions for each given angle of incidence, the cross correlation function is then calculated from the digitized images. The theoretical analysis of the motion of the speckle, as the source is moved, made by Escamilla is verified experimentally. It is found that in contrast with the memory effect line of speckle motion, the speckle pattern produced in the region of observation tracks the backscattering direction.
