    摘要: According to a method for autofocusing on a microscopic sample, measurement light having a local structure is generated. The measurement light is coupled into the microscope beam path, whereby the measurement light is incident on, and reflected by, the sample. The measurement light reflected by the sample is output from the microscope beam path and split among a plurality of component beam paths which pass over optical paths of different lengths to image the reflected measurement light, whereby a plurality of measurement images assigned to different focus positions on the microscope beam path are obtained. At least the measurement image which comes closest to an ideal image of the local structure of the measurement light is selected. Depending on the focus position assigned to the selected measurement image, a focus position to be used on the microscope beam path for the purpose of microscopic imaging of the sample is set.

    摘要: In a method for operating a particle beam microscope, an image of an object region is generated by virtue of a particle beam being directed to a multiplicity of incidence locations within the object region. Particles are detected and a data record is generated. The data record represents the image by a field of pixels, with a position of the pixel in the field representing the incidence location and a pixel value of the pixel representing an intensity of the detected particles at the incidence location. In order to generate an image with an increased number of pixels, at least two images of the object region are generated in succession with a fewer number of pixels and the data records representing the at least two images are supplied to an image processing program which generates the data record representing the image with the greater number of pixels therefrom.

    摘要: An electron beam microscope comprises an electron beam source, a beam tube, a magnetic objective lens, an object holder, a scintillator arrangement, a detector arrangement and a potential supply system. The power supply system supplies: i) the object holder with a potential U1; ii) the beam tube with a potential U2; iii) a pole end of the objective lens with a potential U3; iv) a scintillator body of the scintillator arrangement with a potential; and v) a light detector of the detector arrangement with a potential U5, such that:

    摘要: Operating an ion beam source comprises operating the ion beam source in a beam generation mode and operating the ion beam source in a decontamination mode. Operating in beam generation mode includes generating an ion beam from ions emitted from a tip. Operating in decontamination mode includes supplying power to a heating wire to raise the temperature of the heating wire to a decontamination temperature, measuring a change over time of a physical property indicating a temperature of the heating wire while the power is supplied to the heating wire, and displaying an indication based on the measured change over time of the physical property and/or storing a change value based on the measure change over time of the physical property. The ion beam source comprises the heating wire, a metal reservoir mechanically connected to the heating wire, and the tip mechanically connected to the metal reservoir.

    摘要: Generating an overview image of an object includes, during a first capture duration, scanning regions of the object along a trajectory with illumination radiation, where the trajectory is chosen individually on the basis of properties of the object. First images of the object which together with position data (x, y, z) of an absolute distance measurement system are stored as an individual overview image are captured during the scanning of the trajectory. During a second capture duration, at least regions of the object are scanned with illumination radiation, and second images are captured; regions of the object which have already been imaged during the first capture duration are not imaged again. The first images captured during the first capture duration and the second images captured during the second capture duration are merged to form a resultant overview image of the object.

    摘要: Stereoscopy in which at least one image of a scene is recorded from a first viewing angle, and at least one image of the scene is recorded from a second viewing angle. The scene is recorded multiple times from the first viewing angle. A first combination image is obtained from the various images recorded from the first viewing angle, said combination image according to the stipulation of a comparison algorithm having smaller differences in relation to at least one image also recorded from the second viewing angle or smaller differences in relation to a second combination image obtained from the images from the second viewing angle than each individual image recorded from the first viewing angle. An image of the scene with the depth information is obtained from the first combination image and at least one image from the second viewing angle or the second combination image.

    摘要: A method for preparing data for identifying analytes by coloring one or more analytes with markers in multiple coloring rounds, the markers in each case being specific for a certain set of analytes, detecting multiple markers using a camera, which for each coloring round generates at least one image containing multiple pixels and color values assigned thereto, which may contain color information of one or more markers, and storing the color information of the particular coloring rounds for evaluating the color information, a data point in each case including one or more contiguous pixels in the images of the multiple coloring rounds that are assigned to the same location in a sample.
