| 摘要 |
An optically variable surface pattern is described, comprising a reflection layer (15) and a micromirror arrangement (20) which is formed on the reflection layer (15) and has a multiplicity of semitransparent micromirrors (14), wherein the micromirrors (14) are tilted with respect to the reflection layer (15) such that light (L1) incident on the micromirror arrangement (20) is partly reflected in a first direction as a result of specular reflection on the semitransparent micromirrors (14) and partly reflected in a second direction, different from the first direction, by virtue of passing through the semitransparent micromirrors (14), impinging on the reflection layer (15), being reflected there and thereafter passing through the semitransparent micromirrors (14) again. |
