Disclosed is an optical disk, card or media which comprises: a) a plurality of data structures that are readable by the interrogating beam of light; and b) a composition on or in the optical disk, card or media disposed so that when the optical disk, card or media is used in the optical read-out system, the interrogating beam of light passes through the composition before or after contacting some or all of the data structures. The composition comprises a polymeric matrix with an organometallic complex dissolved therein or with metal, transition metal, metal oxide or transition metal oxide nanoparticles uniformly dispersed therein. The composition is substantially transparent to the interrogating beam and/or is substantially colorless. Alternatively, the composition comprises a solid polymeric matrix with an olefinic compound dissolved or uniformly dispersed therein wherein double bond in the olefinic compound undergoes oxidative cleavage promoted by a transition metal catalyst and a thiophenol or a catalytic amount of a thiyl radical and wherein the composition is substantially transparent to the interrogating beam and/or is substantially colorless.
摘要:
A marking system that includes forming at least one marking in or on an article (420), wherein the image formed is not visible to the unaided human observer, and further contains at least one digital watermark (435). The digitally watermarked image comprises emissive and photoabsorptive portions. The digitally watermarked image is applied using a substance reactive to a predetermined excitation source, and exposure to ultraviolet light. Other traditional techniques, such as printing with fluorescent inks may be used in combination. The digitally watermarked image is subsequently observable upon exposure to the predetermined excitation source. The digitally watermarked image may be observed and decoded by appropriately configured detection systems (400), wherein the information obtained may be used for purposes including, but not limited to, authentication and security of the article or information contained within the article.
摘要:
A photonics data storage system according to the present invention is described comprising a storage material, a data recording/storage apparatus for recording information in this storage material, and an addressing/data reading apparatus for reading the recorded information from this storage material. The photonics data storage system encodes data in the storage medium by an interferometric recording process. The storage medium is composed of a polypeptide material. The polypeptide material comprises a solution of chromium-doped collagen, in which solution α and β chains are predominantly present in proportions such that an α/β ratio is greater than 1.
