Abstract

Apparatus for distinguishing between genuine and counterfeit articles whereby a first optical filter is applied to genuine articles and suspect articles are scanned with the aid of a suitable second optical filter. Scanning of genuine articles incorporating first optical filter with the aid of suitable second optical filter gives rise to optical effects which would not otherwise be apparent.
