| 摘要 |
The invention relates to a colour laser image that can be observed in three dimensions. It comprises a laserable protection sheet (22), a network of lenses (10), coloured sub-pixels in a columnar form (C1,C2,C3), a laser beam that causes the grey shade levels of two colour laser images observable in three dimensions to appear by means of a stereoscopic effect, and a substrate (21). It is all laminated. The axes (31) of the columns of sub-pixels (C1,C2,C3) and the axes (32) of the lenses (L1,L2,L3) are perpendicular. The laser beam scans the sub-pixels according to the axis (32). The invention is applicable to official documents. |
