Abstract
The speckle effect disturbs the measurement of spatial correlation fun ctions in solid polymer samples by light scattering. To be able to ext ract the desired correlations from the measurements, the speckle noise must be suppressed. This is possible by moving the sample during the measurement. In this paper we demonstrate that a sufficient reduction of speckle contrast can be achieved even in samples of restricted dime nsions or with a preferential direction.
