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. The compensator system comprises: - a first lens group for spatially separating the deflected beams of different deflection angle and angular dispersion, - a compensator element having a first surface and a second surface that together work as prisms with tilt angles .beta. and prism opening angles ap 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 while maintaining the angular variation of the beams deflected at different acoustic frequencies. The invention further relates to a corresponding method for compensating for the angular dispersion of electromagnetic beams deflected by an acousto-optic deflector.

Abstract: The invention relates to a method for scanning along a substantially straight line (3D line) lying at an arbitrary direction in a 3D space with a given speed using a 3D laser scanning microscope having a first pair of acousto-optic deflectors deflecting a laser beam in the x-z plane (x axis deflectors) and a second pair of acousto-optic deflectors deflecting the laser beam in the y-z plane (y axis deflectors) for focusing the laser beam in 3D. The invention further relates to a method for scanning a region of interest with a 3D laser scanning microscope having acousto-optic deflectors for focusing a laser beam within a 3D space defined by an optical axis (Z) of the microscope and X, Y axes that are perpendicular to the optical axis and to each other.

Abstract: The invention relates to a method for scanning along a continuous scanning trajectory with a scanner system (100) comprising a first pair of acousto-optic deflectors (10) for deflecting a focal spot of an electromagnetic beam generated by a consecutive lens system (200) defining an optical axis (z) in an x-z plane, and a second pair of acousto-optic deflectors (20) for deflecting the focal spot in a y-z plane being substantially perpendicular to the x-z plane, characterised by changing the acoustic frequency sweeps with time continuously in the deflectors (12, 12') of the first pair of deflectors (10) and in the deflectors (22, 22') of the second pair of deflectors (20) so as to cause the focal spot to move continuously along the scanning trajectory.
