Handsensor for authenticity identification of signets on documents

A sensor for authenticity identification of a luminescent identification feature on a document comprising:

• a beam source and a focusing optics for illuminating the identification feature with a focused beam at a wavelength in the form of an excitation wavelength to optically excite at least a subregion of the identification feature and wherein the identification feature may respond in an optical response signal at a same or different wavelength in the form of a response wavelength,
• a radiation receiver for detecting and evaluating the response wavelength,
• wherein the focused beam is emitted from the beam source and is converted by focusing optics in such a manner that a scanning bar approximately in the form of a line is projected on the surface of the document and having a detection optics and an evaluation unit,
• wherein the optical response signal is passed via detection optics to the evaluation unit which evaluates the optical response signal, and
• wherein the sensor is a manually controlled sensor, the beam source is formed as a laser, and the focusing optics has a lineoptics comprising a cylindrical lens,
• wherein the focused beam is a laser focused beam, which is produced by the laser passed through the lineoptics and is imaged differently in the X-direction and Y-direction on the document.
