On the basement (4) there is an assembling tracery stamp, which is divided into M raster squares (6). Each raster square (6) is divided into N parts (7), and each part (7) is connected to N picture (3) sectors and has a diffractive element (8). In this element (8) there is information about: the optical density of the colour, the level of brightness and observation direction (15).N pictures (3) consist of resolved light clusters which are, for example, the meanings of different letters or numbers, text parts, the images of objects or persons and so on, which are visible in the observation direction (15). The assembling tracery elements can be seen in a reflexed or transient light. The basement (4) can have a stuck label shape (Fig. I). |
