Patent number: 11989376Abstract: In a base element of a waveguide for a detector system at least one portion of radiation passing via the front side and impinging on a diffractive element in the display region is deflected via the diffractive element according to the selection region. The deflected portion is propagated as coupled-in radiation via reflection to an out-coupling region and impinges on the associated out-coupling section of the out-coupling region. The portion of radiation coupled out by an out-coupling section impinges on an associated sensor section of the sensor unit, which continuously measures the intensity of the impinging radiation and supplies the control unit, wherein, according to a change of intensity, which is dependent on positioning an object in front of the front side of the base element and in front of a selection region of the display region, the control unit determines whether the one selection region has been selected.Type: GrantFiled: June 24, 2021Date of Patent: May 21, 2024Assignee: Carl Zeiss Jena GmbHInventors: Martin Thom, Marc Junghans, Roman Kleindienst, Mirko Riethmueller

Publication number: 20230297193Abstract: In a base element of a waveguide for a detector system at least a portion of radiation passing via the front side and incident on the diffractive element in a selection region is deflected via the diffractive element such that the deflected portion is propagated as coupled-in radiation in the base element by reflection to the out-coupling region and is incident on the associated out-coupling section of the out-coupling region. The out-coupling region couples at least a portion of the radiation out of the base element such that it is incident on the associated sensor section of the sensor unit, which continuously measures the intensity of the incident radiation and supplies the control unit. The control unit determines the distance of the object from the front side of the base element according to the measured intensity.Type: ApplicationFiled: June 24, 2021Publication date: September 21, 2023Inventors: Martin THOM, Marc JUNGHANS, Roman KLEINDIENST, Mirko RIETHMUELLER
