<p>The invention relates to a speckle speed sensor using either the balance correlation speed measurement method or the zero cross speed measuring method. The speckle speed sensor comprises at least one light-receiving means (8, 9) for reception of a speckle pattern produced by projection of a laser beam on a moving object (7). The light-receiving means (8, 9) uses a light reception aperture (20) elongated in a direction perpendicular to the direction of movement (5) of the speckle pattern. The elongated aperture configuration is conducive to a diminished measurement error.</p>
