Abstract
An optical identification element for identifying an item. The optical identification element includes a binder material and one or more materials embedded in the binder material. The one or more materials provides an encoded composite X-ray diffraction pattern when illuminated by an X-ray beam. The encoded composite X-ray diffraction pattern is indicative of the item.
Claims33
A method of labeling an item, the method comprising:
- selecting at least one material from a plurality of materials having differing X-ray diffraction patterns;
- embedding the at least one material in a binder material to form at least one optical identification element, the at least one material providing an encoded composite X-ray diffraction pattern when illuminated by an X-ray beam, the encoded composite X-ray diffraction pattern being indicative of a code, the code relating to information about the item;
- and
- physically associating the at least one optical identification element with the item.
1 more element
A method of determining information relating to an item, the method comprising:
- providing an item and an optical identification element that is physically associated with the item;
- illuminating the optical identification element using an X-ray beam;
- detecting a composite X-ray diffraction pattern from the illuminated optical identification element;
- and
- decoding the composite X-ray diffraction pattern to determine a code relating to information about the item.
