FIELD: information technology.
SUBSTANCE: invention relates to image element having substrate with section of surface, upon which plurality of optical elements is arranged. Image element is configured to generate, when illuminated by parallel light from light source, images including plurality of light spots, which are perceived by viewer as suspended above or below said surface section, are located in form of preset motive, and represent actual or virtual images of light source, which illuminates image element.
EFFECT: optical elements therein are formed by refractive and/or reflective optical elements, at least one refractive and/or reflective optical element is associated with each light spot in image consisting of light spots, which contributes to creation of corresponding light spot, when image element is illuminated; wherein for each light spot and optical element associated with it, condition is valid: f/d < 5, where f is height of light spot hanging above or below surface section, and d is diameter of optical element contributing to creation of said light spot.
