Authenticity discrimination device, authenticity discrimination system, counterfeiting preventing structure, and authenticity discrimination method

摘要

Problem to be solved: to obtain a authenticity discriminating device capable of accurately discriminating the authenticity of the object to be authenticated.The authenticity discriminating apparatus 10 comprises a terahertz wave transmitter 21, a terahertz wave receiver 22, and a authenticity discriminator 34.The terahertz wave transmitter 21 sends at least two kinds of terahertz waves having different frequencies.The terahertz wave receiving unit 22 receives at least two kinds of terahertz waves transmitted by the terahertz wave transmitter 21 and reflected by the true discrimination object 5.The authenticity discriminating section 34 compares the intensity of at least two terahertz waves received by the terahertz wave receiving section 22, and determines the authenticity of the authenticity discrimination object 5 based on the comparison result.Diagram
