Sensor for the authenticity of the security features to the value and / or security documents

摘要

It is a method for the authenticity of value - and / or security documents and a corresponding sensor, wherein at least one security element (13, 13 ', 13 ") in or on the value - and / or security document a - and / or is applied. In this case, the security element with a fixedly preset excitation wavelength radiation excited. The security element thereupon emits radiation, wherein the radiation emitted from a detection unit (17) and detected by an evaluation unit (18) is evaluated. The intensity profile of the emitted radiation is in a fixedly predetermined wavelength range above a predetermined time period after the excitation is detected and analyzed for authenticity.
