Abstract

This paper will discuss the problem of the decorrelation of speckle. When a target isirradiated with a coherent laser source, speckle leads to signal variations which is signal noise when the signal can't be adequately signal averaged. Movement of a diffuse incoherent scattering target decorrelates the spatial coherence but a temporal correlation is introduced.
