    摘要: A single-particle localization microscope includes a light source configured to generate illumination light for illuminating a sample region, and an optical illumination system configured to shape the illumination light into a localizing light distribution having a substantially zero intensity minimum at a target point within the sample region. The localizing light distribution is adapted to cause a single particle in a fluorescent state located in the sample region outside the intensity minimum to emit fluorescent light. The optical illumination system is further configured to shape the illumination light into an auxiliary light distribution having a non-zero intensity at the target point such that the auxiliary light distribution is defined in a spatial extent and/or in its shape by the localizing light distribution.

    摘要: A system and method for imaging a tissue sample is provided. The system includes a dome, at least one excitation light source, and at least one light detector. The dome is configured to surround at least a portion of a tissue sample. The dome has interior surfaces that define a dome interior cavity. The excitation light source is configured to produce light at one or more wavelengths. The excitation light source is in photometric communication with the dome. The dome interior surfaces are configured to reflect the light at the one or more predetermined wavelengths. The dome is configured to cause the light at the one or more predetermined wavelengths to be incident to the exposed surface of the tissue sample in a substantially uniform manner. The light detector is in photometric communication with the dome and configured to detect light emitted or reflected from the tissue sample.

    摘要: A method can be used for correcting background signals in captured measurement values of analog detectors, wherein measurement values of an object captured over a reference time period are analyzed and characteristic values of captured background signals are determined. What is characteristic of this is that a threshold value is determined on the basis of at least one characteristic value and by applying a calculation specification; the threshold value is applied to captured measurement values of an analog detector, and only those measurement values which are greater than the threshold value are used for a subsequent signal evaluation. A microscope for carrying out the method according to the invention is also provided.

    摘要: An imaging system and a method of operating an imaging system for imaging a biological target is provided. The imaging system comprises a fluorescence microscope, a light source, an imaging device, a processor, a probe reagent, and a chemical buffer. The method comprises: acquiring, by the imaging device and through the fluorescence microscope, a first image of the biological target at a first time; determining, by the processor, a first value of an image acquisition metric of the first image; determining, by the processor, a first difference between the first value of the image acquisition metric and a predetermined value of the image acquisition metric; adjusting, by the processor, one or more physical parameters of the imaging system based on the first difference, wherein the one or more physical parameters of the imaging system comprise one or more of: an illumination characteristic of the light source, concentration of the probe reagent, and concentration of the chemical buffer; and repeating the steps for a second image acquired at a second time subsequent to the first time.
