IMPROVED LUMINESCENCE CHARACTERISTICS DETECTOR |
摘要 |
The invention discloses an improved method and a device implementing said method for the authentication of security documents or articles carrying luminescent marker compounds which show a time-deferred emission characteristic. The method allows a rapid extraction of characteristic luminescence parameters, such as emission intensity and time constants. The method is not sensitive to perturbations by ambient light and reduces the optical filtering requirements.
