Abstract
An optical assembly includes a volume grating configured to influence a beam direction of at least one light beam, and a switching device arranged in a beam path upstream of the volume grating. The switching device is configured to switch the beam direction and/or beam position of the at least one light beam from a first beam direction and/or beam position, in which the at least one light beam does not impinge on the volume grating at an acceptance angle of the volume grating, to a second beam direction and/or beam position, in which the at least one light beam impinges on the volume grating at the acceptance angle, and/or vice versa.
