Abstract

The identification of individuals, particularly at international border crossings, coupled with the evolving sophistication of identity documents are issues that authorities must contend with.

passports and national ID cards) forego paper substrates for several layers of polycarbonate, allowing security features to be embedded within the documents. These security features may

non-destructive, high throughput manner.

In this publication, we report on the application of optical coherence tomography (OCT) imaging on assessing security features in specimen passports and national ID cards. OCT

allows sub-surface imaging of translucent structures, non-destructively enabling quantitative visualisation of embedded security features.
