Device for guiding light beam with rotation symmetrical beam profile, has transparent flat substrate that is flexible relative to surface normal with lateral input and output coupling regions

摘要

The device has transparent medium into which a light beam enters via an input coupling region, in which light propagates by total reflection or as in a waveguide and from which the beam exits via an output coupling region. The transparent medium is a flat substrate that is flexible relative to the surface normal with at least one lateral edge region via which the beam can be coupled in and one via which the beam passes out of the substrate. The device has light transparent medium into which the light beam enters via an input coupling region, in which light propagation takes place either by total reflection or as a light waveguide and from which the light beam passes out via an output coupling region. The light transparent medium is a flat substrate that is flexible relative to the surface normal and has at least one lateral edge region via which the light beam can be coupled into the flat substrate and one lateral edge region via which the light beam passes out of the flat substrate. Independent claims are also included for the following: a method of spatial shaping of a device for guiding a light beam and an arrangement for guiding a light beam and for coupling to a device for guiding a light beam with a non rotation symmetrical beam profile.
