  • Publication number: 20240035950
    Abstract: The invention is directed to a method for recording a motion trajectory of an individual particle in a sample and to a light microscope performing this method. Starting from an at least approximately known initial position, the particle is scanned with an intensity distribution of a scanning light comprising a local intensity minimum. When illuminated with the scanning light, the particle to be tracked generates a detectable light signal, from the intensity of which updated coordinates of the particle are calculated. According to the invention, the scanning is terminated when a second measured variable detected in parallel satisfies a termination criterion.

  • Publication number: 20230384223
    Abstract: The present invention is a method for spatially highly accurate location determination of individual dye molecules of a fluorescent dye by scanning with an intensity distribution of a scanning light having a local minimum. The invention is characterized by the fact that the scanning is not performed uniformly for all dye molecules, but is individually adapted to the dye molecule to be scanned and, if necessary, to its environment in the sample, in order to achieve the most accurate location determination possible with the smallest possible number of fluorescence photons.

  • Publication number: 20220244515
    Abstract: In a first step of a method of microscopically recording images of samples extending in three dimensions, a first sectional image that is parallel to an optical axis of a microscope objective lens is recorded by scanning a sample with a focused excitation light distribution in a sectional area parallel to the optical axis of the microscope objective, wherein the excitation light distribution is corrected by a correction device according to initial adjustment values for adjustment parameters of an aberration correction function. In a second step, the first sectional image is evaluated. In a third step, new adjustment values for the adjustment parameters are defined. In a fourth step, further image data are recorded by scanning the sample with the focused excitation light distributions, wherein the excitation light distribution is corrected by the correction device according to the new adjustment values for the adjustment parameters of the aberration correction function.

  • Patent number: 10488342
    Abstract: In methods of high-resolution imaging a structure of a sample, the structure being marked with fluorescence markers, the sample is subjected to a light intensity distribution including an intensity maximum of focused fluorescence excitation light to selectively scan partial areas of interest of the sample. Fluorescence light emitted out of the sample is registered and allocated to a respective location of the light intensity distribution in the sample. The subjection of the sample to at least one part of the light intensity distribution is terminated at each location of the light intensity distribution, if at least one criterion of the following criteria is met: (a) a predetermined maximum light amount of the fluorescence light emitted out of the sample has been registered, and (b) a predetermined minimum light amount of the fluorescence light emitted out of the sample has not been registered within a predetermined period of time.
