Abstract
An imaging optical system for a display device that can be fitted on the head of a user and generate an image, with an optical element including an entry surface, and a spectacle lens, which includes a coupling-in section and a coupling-out section spaced apart therefrom. The imaging optical system can guide the generated image fed to the optical element via the entry surface in the optical element, for coupling it from the latter into the spectacle lens, in which it is guided to the coupling-out section and coupled out via the coupling-out section to generate a virtual image. The optical element includes an entry surface, at least one reflecting surface, on which the generated image is reflected, and an exit surface. The entry surface, the at least one reflecting surface and/or the exit surface are formed curved, with the result that the optical element has an imaging property.
