Abstract
A security article includes an optical component that includes a plurality of optical channels with a Fano resonance characteristic. An optical channel, of the plurality of optical channels, is configured to pass a first portion of a first set of light beams (that are associated with a first wavelength range) when the first set of light beams falls incident on at least one of a first surface or a second surface of the optical channel, reflect a second portion of the first set of light beams when the first set of light beams falls incident on the first surface of the optical channel, and reflect at least a portion of a second set of light beams (that are associated with a second wavelength range) when the second set of light beams falls incident on the second surface of the optical channel.
Claims20
A security article reader system, comprising:
- a first light emission device configured to emit a first set of light beams toward a first surface of an optical component of a security article when the security article is placed within an interrogation area of the security article reader system;
- a second light emission device configured to emit a second set of light beams toward a second surface of the optical component of the security article when the security article is placed within the interrogation area of the security article reader system;
- and
- a plurality of sensor elements configured to generate sensor data associated with a plurality of optical channels included within the optical component of the security article when at least some of the first set of light beams or at least some of the second set of light beams are received by the plurality of sensor elements after being transmitted or being reflected by the plurality of optical channels.
A method, comprising:
- identifying, by a security article reader system, sensor data associated with a plurality of optical channels included within an optical component of a security article;
- determining, by the security article reader system and based on the sensor data, one or more respective optical characteristics of the plurality of optical channels;
- determining, by the security article reader system and based on the one or more respective optical characteristics of the plurality of optical channels, identification information associated with the optical component;
- and
- causing, by the security article reader system, one or more actions to be performed based on the identification information associated with the optical component.
A system, comprising:
- a first light emission device configured to emit one or more first light beams toward a first surface of an optical component of a security article;
- a second light emission device configured to emit one or more second light beams toward a second surface of the optical component of the security article;
- and
- one or more components configured to generate sensor data associated with a plurality of optical channels included within the optical component of the security article.
