Abstract
An optical system comprises an imaging holographic optical element, which produces a floating hologram. An upstream light-forming holographic optical element causes spectral filtering of the light.
Claims30
An optical system, comprising:
- an imaging holographic optical element, HOE, configured to generate a floating hologram arranged in a volume outside of the imaging HOE on the basis of light,
- a light source configured to transmit the light along a beam path to the imaging HOE, and
- a light-shaping HOE arranged in the beam path between the light source and the imaging HOE and configured to perform spectral filtering of the light.
