摘要
A laser scanning microscope (SR-LSM) and a method for correcting imaging errors in a laser scanning microscope. The SR-LSM includes an illumination device for providing an illumination spot; a scanner for moving the illumination spot to consecutive scanning positions over a sample to be examined; an adaptive optics unit for controlling a wavefront of the illumination spot with a control device and a detector for determining a spatially resolved imaging spot emitted by the sample. An evaluation unit is provided for determining a point-spread function (PSF) of the imaging spot at each scanning position, whereby a wavefront correction signal determined from the point-spread function (PSF) of a scanning position is supplied to the control device of the adaptive optics unit or is used in digital post-processing of the microscope image (e.g. by means of deconvolution).
