Abstract

A method for operating a point laser-scanning microscope comprises scanning a sample with a focused illumination laser beam; recording a plurality of images by detecting elements being configurable to an intensity mode, in which the recorded images are intensity images gi,j(n) related to photons collected during an entire dwell time of the illumination laser beam on an individual position n, or to a time-resolved mode, in which the recorded images are time-resolved images gi,jt(n,t), the collected photons being discriminated based on their arrival times to individual detecting elements; calculating a fingerprint image a by summing the plurality of intensity images gi,j(n) over all positions n; estimating shift matrices sx and sy from the intensity images gi,j(n); reconstructing at least one of a time-resolved object function ft and an intensity object function f; and visualizing at least one of a high-resolution time-resolved image ft˜ and a high-resolution intensity image f˜.
