Abstract
A substrate is arranged to present a three-dimensional optical image to a viewer, the substrate being formed with a plurality of stereo pairs of grooves or ridges, each such pair of elements providing the viewer with an image of a point at a predetermined distance from the plane of the substrate: the plurality of point images forms the three-dimensional optical image. For example, a pair of linear grooves (14, 16), oriented as shown, reflect incident light (B) into the respective eyes of a viewer, to give the image of a point (P) at a distance (r) behind the substrate surface.
