Abstract
A light guide for an imaging apparatus for generating a virtual image from an initial image with at least two different initial image field regions is provided. The light guide includes an input coupling structure for coupling beams coming from the initial image into the light guide, and an extensive output coupling structure for coupling the beams that were coupled into the light guide out of the light guide. The extensive output coupling structure includes at least two partial faces. Each partial face is assigned to a different one of the initial image field regions and couples out the beams coming from the corresponding initial image field region. The partial faces of the output coupling structure are tilted about two non-parallel axes. The light guide can be part of an imaging apparatus, which can be used in particular in a head-mounted display.
