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″).

Abstract: The object of the invention relates to a method for scanning with an optical beam (50) using a first acousto-optic deflector (15, 15′) having an optical axis along a Z-axis and at least one acousto-optic crystal layer (14), involving directing the optical beam (50) in the first acousto-optic deflector (15, 15′), and deflecting the optical beam (50) along an X-axis perpendicular to the Z-axis by means of the first acousto-optic deflector (15, 15), during which generating a plurality of acoustic chirp signals (30) in the at least one acousto-optic crystal layer (14) of the acousto-optic deflector (15, 15′) by—generating a first acoustic chirp signal (30a) having a duration of τ in the acousto-optic crystal layer (14), then—generating a second acoustic chirp signal (30b) in the acousto-optic crystal layer (14) within a τ period of time counted from the start of the generation of the first acoustic chirp signal (30a).

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 present invention relates to a virtual reality simulator (10) for small laboratory animals (100), in particular rodents, which comprises a head clamping mechanism (20) for securing the laboratory animal (100) and virtual reality glasses (40) with two wings (30), each of the wings (30) having a display (34) and a lens system (36) spaced therefrom and connected together by a light barrier cover (32), and the virtual reality glasses (40) are configured to allow the two wings (30) to align with each of the eyes (101) of the laboratory animal (100), respectively. The invention further relates to a method applying such a simulator (10).
