Abstract
A reflective imaging assembly for viewing an interlaced image to provide a three dimensional or animated visual display. The assembly includes an image element having segments or strips of an interlaced image and includes a reflective substrate including reflectors or mirror elements each having an elongate reflective surface and extending parallel to the segments of the interlaced image. The reflectors focus on the interlaced image to illuminate the segments with reflected light to produce a visual display or effect. Each of the reflectors may have a parabolic cross section to focus reflected light rays onto the segments. A mounting substrate of transparent material is positioned between the image element and the reflective substrate. The mounting substrate abuts the reflectors and provides a planar surface spaced apart from the grooves upon which the image element is provided. Illumination spaces are provided in the image element to facilitate light reaching the reflectors.
