  • Patent number: 11300767
    Abstract: A method for high-resolution scanning microscopy of a sample, wherein the sample is illuminated with illumination light such that the illumination light is focused at a point in or on the sample into an illumination spot. The point is imaged into a diffraction image onto an area detector having detector elements. The area detector has a spatial resolution that resolves a diffraction structure of the diffraction image. The sample is here scanned line-wise in a grid made of rows and columns by displacing the point relative to the sample into different scanning positions with an increment width that is smaller than the diameter of the illumination spot. The area detector is read, and an image of the sample is generated from the data of the area detector and from the scanning positions assigned to said data, said image having a resolution that is increased beyond a resolution limit for imaging.

  • Patent number: 11036038
    Abstract: The invention is based on the object of providing a particularly reliable closed-loop control for a scanner. According to various examples, this object is achieved by an analysis of a system deviation in the frequency space. By way of example, an input signal, which is indicative of a time dependence of the system deviation between an ACTUAL pose and a TARGET pose of a deflection unit of the scanner, can be expanded into a multiplicity of error components and a plurality of frequencies. Then, a corresponding correction signal component can be determined for each of the multiplicity of error components. By way of example, such techniques can be used in a laser scanning microscope.

  • Patent number: 10579576
    Abstract: Forwarding devices and corresponding methods are provided in which a plurality of input data streams are distributed among a plurality of output data streams on the basis of synchronization marking. One example method of forwarding data includes receiving a plurality of input data streams, where at least some of the input data streams include synchronization markers indicating which data of the input data streams are to be output synchronously, in one or more common time segments. Further included in the method is distributing the data to be output synchronously among a plurality of output data streams on the basis of the synchronization markers. The distributing is carried out in such a way that data which, according to the synchronization markers, are to be transmitted in a common time segment are provided in the same time segment in all the output data streams to which the data are to be assigned.

  • Patent number: 10330924
    Abstract: A method for generating a control signal is provided. The method includes the steps of decomposing a desired movement into two partial movements which are separately equalized, and the desired control signal is obtained by summing up the corrected components. The first movement is a slowly (mostly linear) changing long-period (period T1) movement, and the second movement is a short-period (period T2) movement, wherein the period T1 is substantially longer than the period T2. The movements have to a large extent opposing temporal derivations which are nevertheless equal in magnitude so that their sum has a time derivative that is zero. In addition, a method is provided for operating a scanning unit periodically displaceable in an infeed direction by an infeed distance.

  • Publication number: 20160116728
    Abstract: The invention relates to a method for high-resolution luminescence microscopy of a specimen marked with marker molecules, and to a luminescence microscope for performing the method, wherein the marker molecules can be excited to emit luminescence radiation. The method for luminescence microscopy comprises the excitation and imaging of marker molecules and the transmission of a trigger time and a position of the specimen. An optical recording device images the marker molecules in a capture area and transmits data from the imaging to an image capture circuit. The recording device transmits a time for the imaging to a signal former as a trigger time; the trigger time is then transmitted to a data recorder.

  • Patent number: 8943228
    Abstract: A peripheral interface for use with a control computer and a peripheral device. The peripheral interface has a controller receiving an input data stream from the control computer and delivering an output data stream to the peripheral device, the controller obtaining an instruction from the input data stream for a modification of the output data stream. Prior art devices transfer data streams for peripheral devices blockwise by means of DMA using peripheral interfaces. In conventional peripheral interfaces, a burdensome real-time operating system must be used on the control computer in order have a sufficiently short reaction time to bring about a continuous, uninterrupted data stream. The invention achieves the object using a non-real-time operating system.

  • Patent number: 8013288
    Abstract: In a method for correcting a control of an optical scanner (14) which has a beam deflecting element (31) for deflecting a beam of optical radiation and a drive unit (30, 30?) for moving the beam deflecting element (31), said drive unit deflecting a beam of optical radiation directed at the beam deflecting element (31) according to a predetermined target movement using at least one parameter and/or a transfer function, preferably optical, said parameter or transfer function being used to control or regulate the system. In a determination step at least one current value of a drive unit transfer function that reproduces the response of the drive unit (30, 30?) to a predetermined target movement or a change in a target movement is ascertained for at least one frequency, and in a correction step at least one parameter and/or the transfer function is corrected as a function of the current value of the drive unit transfer function.

  • Patent number: 7649683
    Abstract: Process for observing at least one sample region with a light raster microscope by a relative movement between the illumination light and sample via a first scanner along at least one scanning axis essentially perpendicular to the illumination axis wherein several illuminated sample points lie on a line and are detected simultaneously with a spatially resolving detector. At an angle to the plane of the relative movement, a second scanner is moved and an image acquisition takes place by coupling the movement of the first and second scanners and a three-dimensional sampling movement being done by the illumination of the sample. The second scanner is coupled to the movement of the first scanner such that straight and/or curved lines and/or plane and/or curved surfaces are scanned which are extended along at least one scanning direction of the first scanner as well as along the scanning direction of the second scanner.
