Patent ID: 8892400

Claim:
A control unit for a laser scanning microscope comprising a lighting module, a scanning module, a microscope module, and a detection module, wherein light is transmitted from the lighting module to the scanning module, light passes via the scanning module through the microscope module to confocally illuminate a focus volume of a sample ( 22 ), light reflected from the sample or fluorescence emitted from the focus volume passes via the scanning module to the detection module, and the fluorescence emitted from the focus volume is recorded as an image having fluorescence measurement data associated therewith, wherein: said control unit controls the lighting module and the scanning module, divides the image of the focus volume of the sample ( 22 ) into a plurality of image regions corresponding to regions (B mn ) of the sample, and distinguishes regions of the sample that are relevant for evaluating the fluorescence measurement data recorded in the recording step from regions of the sample that are non-relevant by determining a degree of suitability for at least one of the regions (B mn ) of the sample ( 22 ), wherein the degree of suitability quantifies the suitability of a corresponding region for a correlation analysis for evaluating the fluorescence measurement data of the sample ( 22 ).
