    Abstract: The invention relates to a method for correcting motion artifacts of in vivo fluorescence measurements using a 3D laser scanning microscope containing two pairs of orthogonally arranged acousto-optic deflectors, the method comprising: selecting a region of interest, selecting a plurality of guiding points along the region of interest, extending the guiding points to objects selected from scanning lines and/or surface elements and/or volume elements which, together, substantially cover the region of interest, repeatedly scanning the objects by generating continuous drifts to cover the objects, projecting the obtained scanning data to frames and obtaining a time series of the frames, correcting motion artifacts by shifting the data of the successive frames with respect to each other so as to maximize fluorescence cross correlation between the data of the frames.

    Abstract: The invention relates to a compensator system adapted to compensate for the angular dispersion of electromagnetic beams deflected by at least one acousto-optic deflector of an optical system, wherein the angular dispersion of each deflected beam is dependent on the deflection angle obtained by the deflecting acoustic frequency of the acousto-optic deflector, characterised in that the compensator system comprises: - a first lens group for spatially separating the deflected beams of different deflection angle and angular dispersion by focusing the beams substantially into the focal plane, - a compensator element having a first surface and a second surface, and being arranged such that the first surface of the compensator element lies substantially in the focal plane of the first lens group, and the first and second surfaces of the compensator element have nominal radiuses R 1 and R 2 that together work as prisms with tilt angles β and prism opening angles α p that vary with the distance from the optical axis so as to compensate for the angular dispersion of the spatially separated deflected beams, - a second lens group arranged so as to substantially parallelise the different wavelength components of each deflected beam exiting the compensator element while maintaining the angular variation of the beams deflected at different acoustic frequencies. The invention further relates to method for compensating for the angular dispersion of electromagnetic beams deflected by at least one acousto-optic deflector of an optical system, wherein the angular dispersion of each deflected beam is dependent on the deflection angle obtained by the deflecting acoustic frequency, characterised by - spatially separating the deflected beams of different deflection angle and angular dispersion by focusing the beams via a first lens group substantially into the focal plane of the first lens group, - compensating for the angular dispersion of the spatially separated deflected beams in accordance with the angular dispersion of the given beam, - substantially parallelising the spectral components of each deflected beam while maintaining the angular variation of the beams deflected at different acoustic frequencies.
