Abstract

An optical system for transmitting a source image includes a light guide, which defines a light transmission channel, an optical coupling arrangement and an optical decoupling arrangement, the coupling arrangement being designed to couple light emerging from the source image into the light guide arrangement in such a way that the light can propagate in the light guide arrangement by total reflection, and the decoupling arrangement being designed to decouple light that has propagated in the light guide arrangement from the light guide arrangement. The light guide arrangement comprises an optical deflection device, which, as viewed in the direction of propagation of the light in the light guide arrangement, is arranged between the coupling arrangement and the decoupling arrangement and is designed to deflect light ray bundles, emerging from the coupling arrangement at different beam angles and impinging divergently on the deflection device, in bundled manner towards the decoupling arrangement.
