Abstract
We provide an apparatus and method for analysing a security document. An x-ray source is adapted to illuminate at least one inspection region of the security document when located at an inspection position. An x-ray detector adapted to receive x-rays from the at least one inspection region of the document and to generate a corresponding detector response. A processor analyses the detector response and generates an output signal indicative of the structure of the document in the at least one inspection region.

Apparatus for analysing a security document, comprising:
- an x-ray source adapted to illuminate at least one inspection region of the security document when located at an inspection position;
- an x-ray detector adapted to receive x-rays from the at least one inspection region of the document and to generate a corresponding detector response;
- and
- a processor adapted to analyse the detector response and to generate an output signal indicative of the structure of the document in the at least one inspection region.
A method of analysing a security document, the method comprising:
- illuminating at least one inspection region of the security document with x-rays from an x-ray source, whilst the document is in an inspection position;
- receiving x-rays from the at least one inspection region at an x-ray detector adapted to generate a corresponding detector response;
- and
- analysing the detector response so as to generate an output signal indicative of the structure of the document within the at least one inspection region.
