APPARATUS AND METHOD FOR DETECTING COUNTERFEIT

摘要

The present invention provides a device to detect a counterfeit object, which includes: a printing module forming a photonic crystal, having a single layer nanostructure, in an object by using nanoparticles; a light source module radiating light to the photonic crystal; a reflective light sensing module generating sensing information by sensing reflective light emitted from the photonic crystal to which the light is radiated; and a detecting module determining whether the object is counterfeit or not by comparing the sensing information to pre-stored counterfeit detection information. Therefore, the present invention is capable of simplifying a manufacturing process by forming a single layer structure with a nanoparticle self-control assembly method.
