Patent number: 8214561Abstract: A peripheral interface and process for data transfer, especially for laser scanning microscopes. The peripheral interface permits a gap-free transfer of data with high transmission speed using a non-real-time-enabled operating system of the control computer. A peripheral connection for a peripheral device and a control unit serving for one-way transmission of a predetermined amount of data from the control computer to the peripheral device and/or vice versa accesses via a system bus of a control computer, a work memory region of the control computer serves as buffers preassigned to it, where the control unit prepares for the control computer a progress report of the transfer for retrieval and the control unit of the control computer is informed of the progress of the processing of the buffer independently of the transfer.Type: GrantFiled: February 13, 2009Date of Patent: July 3, 2012Assignee: Carl Zeiss MicroImaging GmbHInventors: Andreas Kuehm, Nico Presser, Gunter Moehler

Patent number: 7869123Abstract: Specimen laser-scanning microscope with raster scanning illumination and detector modules, which illuminates and detects a specimen by raster scanning. A real-time control device (device) performs synchronous reading-out with the raster scanning pixel cycle. A data port serially communicates with the device using a bidirectional high-speed data stream and with the resources via a serial, bidirectional high-speed data stream with a data conversion to/from parallel to serial. The high-speed data stream is made up of data packets with data bits and type bits and no additional header or protocol bits. The data bits contain data from/on the resources and the type bits code the type of data. Type information is stored in the resources as well as the device. The type information defines processing functions for data types coded by the type bits, and the resources and/or the device determine the data type using type bits and process data coded in the data bits.Type: GrantFiled: May 31, 2007Date of Patent: January 11, 2011Assignee: Carl Zeiss MicroImaging GmbHInventors: Gunter Moehler, Mirko Liedtke

Patent number: 7145652Abstract: A microscope with optical components which are provided in the illumination beam path and/or observation beam path and/or detection beam path for exerting different spectral influences on at least one of the beam paths mentioned above. An arrangement comprising a light source emitting a plurality of wavelengths and at least one spectral sensor detecting the light of this light source after interacting with a component are provided, preferably outside these beam paths. The interaction is carried out by transmission or reflection of the light by the component. The detected values of the spectral sensor are compared to pre-stored values and correlation with pre-stored values is advantageously carried out in a storage.

Patent number: RE41666Abstract: A process for confocal microscopy is disclosed in which laser light is coupled into a microscope beam path, directed successively with respect to time onto different locations of a specimen, and an image of the scanned plane is generated from the light reflected and emitted by the irradiated locations. A change in the spectral composition and in the intensity of light is are carried out during the deflection of the laser beam from location to location, while the deflection continues in an uninterrupted manner. In this way , so that at least two adjacent locations of the specimen located next to one another are acted upon by light with different spectral characteristics and by laser radiation of different intensity. By periodically interrupting the coupling in of the laser light during the deflection of the microscope beam path, it is made possible that only selected portions of the image field are acted upon by the laser radiation. A laser scanning microscope for carrying out this process is also disclosed.Type: GrantFiled: October 7, 2004Date of Patent: September 14, 2010Assignees: Carl Zeiss Jena GmbH, European Molecular Biology LaboratoryInventors: Ulrich Simon, Sebastian Tille, Gunter Moehler, Stefan Wilhelm, Ulrich Meisel, Ernst Stelzer
