Abstract

A system to authenticate and identify items is described herein. An example apparatus includes an illuminating source to illuminate a sample with a first emission of light having a peak wavelength at a first wavelength and a second emission of light having a peak wavelength at a second wavelength, a photo element to detect a first optical response emitted by the sample after the first emission of light and to detect a second optical response emitted by the sample after the second emission of light, and an identifier to identify the sample based on the first optical response and the second optical response.
