    摘要: This inventive method assures the authenticity of drugs or other valuable substances that reside within product containers, such as syringes. The method includes initially measuring the 3D topology of the glass surface while determining the distance to the glass surface. Thereafter, a desired 3D code is written below the glass surface with a pulsed laser system. The written 3D code is readable using optical coherence topography (OCT) or parallel optical coherence tomography (pOCT) to verify the authenticity of the product container. A system uses this method with a plurality of syringes held within a tray, and a writing apparatus that moves relative to the tray to write a predetermined 3D code on each of the syringes held in the tray, during processing of the syringes along a process line while in the tray.

    摘要: An information bearing device comprising a data bearing pattern, wherein the data bearing pattern comprises a plurality of data defining elements, the data defining elements being spatially distributed to define a set of spatial frequency data, and the set of spatial frequency data comprising a plurality of frequency data elements (F1, F2, . . . , Fn); and wherein each frequency data (Fi) has a data frequency magnitude (fi) and a data frequency angle(θi), the data frequency magnitude being above a first characteristic spatial frequency (fA) which corresponds to a characteristic frequency of a staple or commonplace image reproduction apparatus, the characteristic frequency representing an image data frequency above which reproduction quality by the staple or commonplace image reproduction apparatus begins to drop substantially.
