Self-targeting reader system for remote identification |
摘要 |
A method and apparatus for identifying articles is disclosed. The method includes steps of: (a) providing a plurality of articles, each of the articles having at least one portion that includes a photonically active material; (b) for each article, illuminating the at least one portion with light from a stimulus source; (c) identifying a location of the at least one portion by detecting an emission from the photonically active material; (d) pointing an excitation source at the identified location; and (e) illuminating the at least one portion within the identified location with light from the excitation source. A next step detects an information-encoded emission from the photonically active material in response to the light from the excitation source. An optional step (g) sorts the articles based on the detected emission.
