Abstract

A system for decoding energy peaks of an identifier comprises an decoder. The decoder is configured to receive a first reference peak position and a second reference peak position associated with an identifier. The identifier comprises a rugate microtag. The encoder is configured to receive a set of data pattern peak positions associated with the identifier. The decoder is configured to determine a set of adjusted data pattern peak positions based on the first reference peak position and the second reference peak position.
