PARALLAX EFFECT SECURITY ELEMENT
First Claim
1. A security element, comprising:
- an optical system, comprising;
a transparent or translucent substrate;
on the side of a first face of the substrate a combined image comprising a plurality of interleaved coded images; and
an exposure screen overlaid on the combined image configured to enable observation of the coded images upon a change of the direction of observation of the security element in relation to the optical system,the exposure screen being;
situated on the side of a second face of the substrate, opposite from the first face, the optical system then comprising a background disposed in such a way that the exposure screen is between the background and the substrate or that the combined image is between the background and the substrate, the exposure screen, the combined image and the background having different colors.

Abstract
The present invention relates to a security element (1), comprising: an optical system, comprising: a transparent or translucent substrate (2), on the side of a first surface (2a, 2b) of the substrate (2) is a combined image (I) comprising a plurality of encoded interleaved images (I1), a exposing screen (4) placed on top of the combined image, enabling the encoded images (I1) to be observed during a change in the direction of observing the security element (1) relative to the optical system, the exposing screen (4) being: located on the side of the first surface (2a, 2b), the combined image then being located between the exposing screen (4) and the substrate (2), in which case the security element (1) comprises, on the side of the second surface (2a, 2b), a reflective surface that enables the encoded images (I1) to be observed through exposing screen (4).
