| 英文摘要 | When THz light propagates through a banknote of RMB, which is transparent for THz radiation, the transmitted THz radiation carries signals of security features. In this letter, experimental researches on banknote discrimination by continuous-wave THz imaging are demonstrated by using of an optically-pumped THz laser (OPTL, Sifir-50, Coherent) and a pyroelectric camera (PyrocamIII). Real-time THz images of water-mark and security thread are achieved and comparison of real and fake security features is shown. THz images of genuine notes are clear and stable, while that of forged notes are confused and random. Results show that the authenticity of the tested banknote can be reliably determined by comparing its THz imaging with that ofgenuine banknotes. This research is only the first step in demonstrating the feasibility of banknote discrimination by THz imaging, however, THztechnology provides a novel method of banknote discrimination. |
