Abstract
An optical system comprises a plurality of optical channels. A control unit can switch light sources of the optical channels separately on and off. In this way, different image motifs of a hologram can be illuminated by a number of different illumination sources of at least one imaging holographic optical element.
Claims19
An optical system, comprising:
- at least one imaging holographic optical element, HOE, configured to generate a floating hologram on the basis of light, said hologram being reconstructed in a volume outside of the at least one imaging HOE,
- a plurality of optical channels each comprising a light source and a beam path configured to guide the light along the respective beam path to the at least one imaging HOE, and
- a controller configured to individually control the light sources for the plurality of optical channels.
A computer-implemented method, comprising:
- an individual control of a plurality of light sources in an optical system on the basis of one or more decision criteria,
- wherein the plurality of light sources are assigned to a plurality of optical channels of the optical system, which each comprise an associated beam path and are configured to guide the light transmitted by the respective light source of the plurality of light sources toward at least one imaging holographic optical element, HOE, of the optical system,
- wherein the at least one imaging HOE is configured to generate a floating hologram in a volume outside of the at least one imaging HOE on the basis of the light.
