Patent number: 10048481Abstract: A method for operating a scanning microscope and for determining point spread functions, with which sample images are recorded with the scanning microscope. The method includes scanning a sample with at least one illuminating light beam; recording at least one sample image with a detector device during a scan by the illuminating light beam; and comprising the point spread function, with which a sample image is recorded, from the at least one sample image. A detector device having receiving elements is used, where the distance between the receiving elements is smaller than a diffraction disk that generates a sample point on the detector device. Detector signals, generated by means of the receiving elements, are read out for each of the different positions of the illuminating light beam on the sample, as a result of which the scanning of the sample allows the detector signals, which are read out, to generate a plurality of sample images.Type: GrantFiled: October 10, 2014Date of Patent: August 14, 2018Assignee: Carl Zeiss Microscopy GmbHInventors: Ingo Kleppe, Yauheni Novikau, Ralf Netz, Michael Kieweg, Christoph Nieten

Publication number: 20180020912Abstract: An optical coherence tomograph that provides wavelength tunable source radiation and an illumination and measurement beam path, a dividing element that divides source radiation into illumination radiation and reference radiation, and collects measurement radiation. The illumination and measurement beam path has scanner. A detection beam path receives measurement radiation and reference radiation and conducts them onto at least one flat panel detector in a superposed manner. A beam splitter separates the measurement radiation from the illumination radiation. The beam splitter conducts the separated measurement radiation to the detection beam path and sets the numerical aperture of the illumination of the illumination field in the eye. An optical element sets the numerical aperture with which the measurement radiation is collected in the eye and a multi-perforated aperture defines the size of an object field and a number of object spots, from which the measurement radiation reaches the flat panel detector.Type: ApplicationFiled: January 28, 2016Publication date: January 25, 2018Applicant: CARL ZEISS MEDITEC AGInventors: Daniel Bublitz, Christoph Nieten
