摘要
A light guide for guiding light for an HMD includes at least one input coupling structure and at least one output coupling structure. The output coupling structure can be oriented such that for all the rays that are coupled out by the output coupling structure and for which the wave vector k has a negative ratio ky/kxz after they have been coupled out, the wave vector k in the light guide has a ratio of ky/kxz of greater than −0.2, and/or that for all the rays that are coupled out by the output coupling structure and for which the wave vector k has a positive ratio ky/kxz after they have been coupled out, the wave vector k in the light guide has a ratio of ky/kxz of less than +0.2.
