With significant advances in printing and production equipment, the production and circulation of inauthentic documents have become increasingly sophisticated. Although there are advanced detection and analysis methods for counterfeit documents and artifacts, most require expensive laboratory bench-top equipment that require detailed training, and are usually slow to collect and analyze data. Some of these need elaborate sample handling and positioning, and frequently cannot be taken into the fleld. This technical note presents a simple fluorescence-based hyperspectral-imaging method of detecting and analyzing the quality or authenticity of documents and artifacts using the VERDE vis 300 Simultaneous Hyperspectral camera from HORIBA Scientific. This method requires no more training than that required to operate a consumer-grade point-and-shoot camera. All the image and spectral data are collected in one shot, a time saving benefit. Although the example shown here uses paper currency, the method is applicable to any targets that fluoresce or reflect characteristic radiation that can be used for the identiflcation of specific features.
