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 a laser, and a camera. The laser is configured to direct laser 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.
Claims9
A system comprising:
- a plurality of mobile optical identifiers, each mobile optical identifier comprising:
- an optical substrate;
- and
- a volume hologram in the optical substrate;
- and
- a reader for the optical identifiers, the reader comprising:
- a housing;
- at least one illumination device in the housing;
- a camera in the housing;
- and
- a fixed optical identifier between the at least one illumination device and the camera in the housing, wherein the fixed optical identifier comprises an optical substrate and a volume hologram in the optical substrate,
- wherein the housing defines a slot for receiving one of the plurality of mobile optical identifiers;
- wherein the at least one illumination device is configured to direct light into at least one of the fixed optical identifier and the mobile optical identifier in the slot of the housing to produce an image of corresponding to at least one volume hologram of the mobile or fixed optical identifier 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.
