The invention relates to a security element (1) which, prior to the incorporation thereof into an object, particularly a security document, comprises a substrate (6) bearing at least: an optical structure (4) producing at least one image of at least one comparison pattern and/or producing image points of a light source illuminating the optical structure; and a reference pattern (3), in which the optical structure (4) and the reference pattern (3) are borne by the substrate (6) in order to allow the simultaneous observation of an image provided by the optical structure (4) and of the reference pattern (3).
