    • A method and apparatus for drug product tracking (or other pharmaceutical, health care or cosmetics products, and/or the packages or containers they are supplied with) using diffraction grating-based encoded optical identification elements 8 includes an optical substrate 10 having at least one diffraction grating 12 disposed therein. The grating 12 has one or more collocated pitches Λ which represent a unique identification digital code that is detected when illuminated by incident light 24. The incident light 24 may be directed transversely from the side of the substrate 10 (or from an end) with a narrow band (single wavelength) or multiple wavelength source, and the code is represented by a spatial distribution of light or a wavelength spectrum, respectively, or a combination thereof. The encoded element 8 may be used to label any desired item, such as drugs or medicines, or other pharmaceutical or health care products or cosmetics. The label may be used for many different purposes, such as for sorting, tracking, identification, verification, authentication, anti-theft/anti-counterfeit, security/anti-terrorism, or for other purposes. In a manufacturing environment, the elements 8 may be used to track inventory for production information or sales of goods/products. Such labeling provides product identification at the pill or liquid medicine level, which provides traceability of these products to their manufacturer, thereby reducing counterfeit products in the marketplace. Also, the elements 8 may be incorporated into a film, liquid, coating or adhesive tape at attached to the product package.
    • 使用基于衍射光栅的编码光学识别元件8的药物追踪(或其他药物,保健或化妆品产品和/或其提供的包装或容器)的方法和装置包括具有至少一个 设置在其中的衍射光栅12。 光栅12具有一个或多个并置的间距Λ,它们表示当被入射光24照射时被检测到的唯一识别数字码。入射光24可以从基板10的一侧(或从一端)横向引导到 窄波段(单波长)或多波长光源,代码分别由光或波长光谱的空间分布或其组合表示。 编码元件8可以用于标记任何期望的物品,例如药物或药物,或其它药物或保健产品或化妆品。 该标签可用于许多不同的目的,例如用于分类,跟踪,识别,验证,认证,防盗/防伪,安全/反恐,或用于其他目的。 在制造环境中,元件8可用于跟踪生产信息的库存或货物/产品的销售。 这种标签在药丸或液体药物级别提供产品鉴定,这些产品可以向制造商提供可追溯性,从而减少市场上的假冒产品。 此外,元件8可以结合到附接到产品包装上的膜,液体,涂层或胶带中。
