Patent number: 11886947Abstract: A method for uniquely marking an object, wherein a random distribution of individual pigment domains is applied to a surface of the object, and wherein a list of distances of the individual pigment domains from one another is measured and stored in a database. Also a corresponding method for identifying an object by: capturing an image of the pigment domains, identifying the two-dimensional coordinates of each pigment domain captured in the image, determining the two-dimensional distance of each pair of two pigment domains and/or the angle of each triplet of pigment domains, storing the distances and/or angles determined in the step before in a list, storing the list in the database, the list enriched with meta-information about the manufacturing and/or finishing parameters of the object, applying a database identification as an information unit to the surface of the object, the information unit uniquely assignable to the database.Type: GrantFiled: November 17, 2021Date of Patent: January 30, 2024Assignee: LEUCHTSTOFFWERK BREITUNGEN GMBHInventors: Thomas Bitzer, Benedikt Daumann, Dominik Uhlich

Publication number: 20210293620Abstract: The disclosure relates to a spectrometer, comprising: an illumination device for illuminating a spectrometric measurement region; a detection unit for detecting electromagnetic radiation coming from the spectrometric measurement region; and a spectral element, which is arranged in the beam path between the illumination device and the detection unit. The illumination device comprises: a light emitting diode having a first central wavelength, which is designed to emit first electromagnetic radiation having a first spectrum; and a luminescent element for converting a first component of the first electromagnetic radiation having the first spectrum into second electromagnetic radiation having a second spectrum. The first central wavelength is 550 nm or 3000 nm or has a value between 550 nm and 3000 nm. The first spectrum and the second spectrum have an overlap.Type: ApplicationFiled: July 23, 2019Publication date: September 23, 2021Inventors: Martin Husnik, Martin Dinser, Marc Schmid, Dominik Uhlich
