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: 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).
