Abstract

The contrast of a totally integrated fringe pattern generated by a partially developed gaussian speckle is studied. It is shown that fluctuations of the integrated fringe pattern obtained in Young's interference experiment are determined by the sum of variance and covariance of the speckle pattern intensity. In this way we have studied indirectly the second-order statistics of the partially developed speckle in the far-field region. The theoretical results are compared with experimental data.
