The speckle pattern produced by laser light scattered from a moving diffuse surface is described with linear system analysis. The mathematical procedures are greatly simplified by operator algebra. Results cited in the literature are shown to be special cases, derived under simplifying assumptions, from the general expressions obtained in the present work.
