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).

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.

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 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 R1 and R2 that together work as prisms with tilt angles ß 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 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.
