Embodiment Construction

[0028] figure 1 and 2 A first exemplary embodiment of the optical arrangement according to the invention is shown schematically. The optical arrangement has a volume grating 1 designed as an AOD for influencing the beam direction of the two light beams 2 , 3 . In this case, light beams 2 and 3 are guided through volume grating 1 . In all the exemplary embodiments described here and also in other exemplary embodiments, at least two light beams 2 , 3 can be guided through the volume grating 1 . With regard to the flexible switching of the light beam 2 guided through the volume grating 1 between the two illumination arrangements, a switching device 4 is provided in the beam path upstream of the volume grating 1 for changing the beam direction of the light beam 2 from the first Conversion of a beam direction to a second beam direction in which the light beam 2 does not impinge on the volume grating 1 at the acceptance angle of the volume grating 1, and vice versa. The light be...

Abstract

In order to achieve a flexible change between different orders of diffraction of a light beam guided through a volume grid (1), an optical assembly with a volume grid (1) is provided for influencing the beam direction of at least one light beam (2). The system is characterized in that a switching device (4) is arranged in a beam path in front of the volume grid (1) for switching the beam directionand/or beam position of at least one light beam (2) from a first beam direction and/or beam position, in which the at least one light beam (2) is not incident on the volume grid (1) at an acceptanceangle of the volume grid (1), to a second beam direction and/or beam position, in which the at least one light beam (2) is incident on the volume grid (1) at the acceptance angle, and/or vice versa. The invention additionally relates to a method for influencing the beam direction of at least one light beam (2), in particular using the aforementioned optical assembly.

Description

technical field [0001] The invention relates to an optical arrangement comprising a volume grating for influencing the beam direction and / or the beam position of at least one light beam. [0002] Furthermore, the invention relates to a method for influencing the beam direction and / or the beam position of at least one light beam. Background technique [0003] Optical arrangements and methods for influencing the beam direction of at least one light beam are known from practice, wherein volume gratings, for example acousto-optical deflectors, AODs are used for influencing the beam direction of at least one light beam. For example, a light beam of a laser can be fed into such an AOD in such a way that the AOD extends optimally. In this case, the light beams of different lasers are often influenced. In such scenarios, problems can arise when multiple lasers are activated simultaneously. The frequencies applied to the AOD act differently on the individual light beams, which hav...
