ЭЛЕМЕНТ ЗАЩИТЫ С ДИФРАКЦИОННЫМИ СТРУКТУРАМИ |
摘要 |
The device is a plastic laminate with a mosaic surface pattern of surface elements with a light reflective boundary between a molded layer and a covering layer. The molded layer has optically active structures at the boundary. The surface pattern (12) has at least one pair of surfaces with first and second elements (14,15) with a diffraction structure formed by superimposing a grid structure and a relief structure. |
