Introduction

Thomas Leitner is an accomplished inventor based in Constance, Germany. He has made significant contributions to the field of document verification, holding 2 patents that showcase his innovative approach to ensuring the authenticity of secured documents.

Latest Patents

One of his latest patents is a "Device for verifying documents." This document-examining apparatus is designed to automatically examine the authenticity elements of secured documents. It features a compound slide that can be moved in both the X and Y directions, on which the necessary components for evaluating distinguishing authenticity features are mounted. The X slide is mounted on a Y slide, allowing for a first group of evaluating units to assess diffraction elements on a document. Additionally, a second group of evaluating components can be mounted on the Y slide to evaluate text, an IR field, and/or a photographic field. The device also includes a source of UV radiation to examine distinguishing fluorescence features of a document, which can be evaluated by a stationary unit or by the unit on the X slide.

Another notable patent is the "Device for evaluating diffractive authenticity features." This apparatus evaluates distinguishing authenticity features comprising diffraction elements on a document illuminated by a light source. The authenticity element diffracts the beam from the illumination source, projecting it onto an evaluating unit. To ensure independence from the nature and location of the diffraction pattern, the pattern derived from the document is projected onto a screen, and the image is recorded and evaluated by a camera.
