<p>The invention relates to a method for examining a security feature in security documents or materials, which security feature turns electroluminescent in an excited state. For this purpose, the electroluminescence of the security feature is initially excited by means of a stimulator. Subsequently, the distance between stimulator and electroluminescent security feature, and the intensity of the emission generated by the electroluminescence are measured. Lastly, the measured intensity is adjusted on the basis of the measured distance in order to generate an intensity value that is scaled to a predetermined basic distance and is distance-adjusted. The invention further relates to a device for carrying out said method.</p> |
