Researchers at the University of Kent have found that optical coherence tomography (OCT) imaging technology can be utilized to distinguish between legitimate and counterfeit travel documents.
They describe their work in "Sub-Surface Characterization of Latest-Generation Identification Documents Using Optical Coherence Tomography," published in the journal Science & Justice.
The researchers demonstrate that OCT can perform quantitative, non-destructive, high resolution sub-surface analysis of multi-layered identification document, with a high imaging throughput and high-density volume. The technology typically takes less than 10 seconds to detect counterfeit documentation.
"We believe that the application of OCT can be used by multiple stakeholders in the field, especially forensic scientists working to validate suspected counterfeit documents and document manufacturers as a non-destructive method of quality control," says Roberto King, chief technology officer at forensics science technology company Foster and Freeman.
