Patent number: 10393501Abstract: A device for determining a 3D structure of an object having first and second laser emitters which generate laser radiation with first and second different wavelengths, respectively. A first beam splitter splits the laser radiation of each laser emitter into reference and illuminating radiation. The illuminating radiation is adapted to impinge on the object to be measured, be reflected by the object as object radiation, and interfere with the reference radiation to form interference patterns. A detector receives the interference patterns. A selection hologram deflects object radiation which impinges on it within a predefined incidence angle range and passes object radiation which impinges on it outside of the incidence angle range undiffracted. The undiffracted radiation either passes by the determination area of the detector or impinges on the determination area at an angle outside the determination angle range.Type: GrantFiled: May 2, 2017Date of Patent: August 27, 2019Assignee: VOCO GMBHInventor: Alexander Knüttel

Patent number: 9835435Abstract: Apparatus for detecting a 3D structure of an object, comprising at least three laser emitters and a beam splitter that splits the laser radiation of the laser emitters into a reference radiation and an illumination radiation. The illumination radiation strikes the object to be measured, is reflected by the object as object radiation and interferes with the reference radiation. A detector receives the interference patterns formed from the interference of the reference and object radiation and an analysis unit analyzes the interference patterns. At least two of the laser emitters emit laser radiation in the invisible range and the analysis unit detects the object in three dimensions based on the interference patterns of the invisible laser radiation. At least one of the laser emitters emits colored laser radiation and the analysis unit deduces the object's color based on the intensity of the colored object radiation reflected by the object.Type: GrantFiled: May 20, 2015Date of Patent: December 5, 2017Assignee: Voco GmbHInventor: Alexander Knüttel

Patent number: 5962852Abstract: Method for determining an analyte in a scattering matrix. In a detection step detection measurements are made in which light is irradiated into the matrix as primary light and light leaving the scattering matrix is detected as secondary light, in order to determine as a measurement quantity a measurable physical property of the light which is variable due to the interaction of the light with the matrix. Information on the presence of the analyte in the matrix is determined in an evaluation step. The determination of optically weakly absorbing analytes against a strongly absorbing interference background is improved by the use of two selection methods for the depth selective detection of the secondary light in combination with one another.Type: GrantFiled: July 28, 1997Date of Patent: October 5, 1999Assignee: Roche Diagnostics GmbHInventors: Alexander Knuettel, Dirk Boecker, Matthias Essenpreis
