Abstract
A system includes a plurality of optical identifiers and a reader for the optical identifiers. Each optical identifier has an optical substrate and a volume hologram (e.g., with unique data, such as a code page) in the optical substrate. The reader for the optical identifiers includes an illumination source (e.g., a laser), and a camera. The illumination source is configured to direct light into a selected one of the optical identifiers that has been placed into the reader to produce an image of the associated volume holograms at the camera. The camera is configured to capture the image. The captured image may be stored in a digital format by the system.
Claims23
A system comprising:
- a plurality of optical identifiers, each optical identifier comprising:
- an optical substrate;
- and
- a volume hologram in the optical substrate;
- and
- a reader for the optical identifiers, the reader comprising:
- an illumination source;
- and
- a camera,
- wherein the illumination source is configured to direct light into a selected one of the optical identifiers to produce an image of a corresponding one of the volume holograms at the camera, and
- wherein the camera is configured to capture the image, wherein the captured image is stored in a digital format by the system.
A method comprising:
- directing light from a laser into a first optical identifier, wherein the first optical identifier comprises an optical substrate and a volume hologram in the optical substrate;
- and
- capturing an image of the volume hologram produced by the light from the laser with a camera;
- and
- storing the captured image in a digital format in a non-transitory, computer-based memory.
