Abstract: A method for scanning along a substantially straight line (3D line) lying at an arbitrary direction in a 3D space with a given speed uses 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. Further, a method for scanning a region of interest uses 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 subject of the invention relates to an acousto-optic deflector with a layered structure (10), the essence of which is it comprises at least two acousto-optic crystals (12), to each of which at least one electro-acoustic transducer (14) is connected, and the adjacent crystals (12) are separated by an acoustic isolator (16). The subject of the invention also relates to a method for deflecting an optical beam using an acousto-optic deflector (10), characterised by that the acousto-optic deflector (10) comprises at least two acousto-optic crystals (12′, 12″), among which a first acoustic wave (15′) is created in a first acousto-optic crystal (12′) using a first electro-acoustic transducer (14′) connected to the first acousto-optic crystal (12′), and a second acoustic wave (15″) is created in a second acousto-optic crystal (12″) using a second electro-acoustic transducer (14″) connected to the second acousto-optic crystal (12″) and arranged between the first acousto-optic crystal (12′) and the second crystal (12″).
