Abstract
A system and method for identifying information related to an object. A radiation emitter is configured to direct radiation toward an object, the object including one or more diffraction gratings including encoded information related to the object. A detector is configured to receive modified radiation from the one or more diffraction gratings on the object and transfer the received modified radiation to a processing device operably connected to the detector. The processing device is configured to process the modified radiation and decode the information related to the object encoded in the one or more diffraction gratings.
