Abstract
A wavefront manipulator which comprises a holographic assembly and an optical element is provided. The optical element includes at least one surface, which is totally reflective for an ascertained range of incidence angles, for emitting light waves onto the holographic assembly. The holographic assembly includes at least one reflection hologram for reflecting light waves emitted onto the holographic assembly via the optical element. The optical element includes a coupling device for coupling light waves into the wavefront manipulator. The coupling device includes at least one prism.

1-19. (cancelled)
A wavefront manipulator, comprising:
- a holographic arrangement;
- and
- an optical element that radiates light waves onto the holographic arrangement, the optical element comprising at least one face providing total-internal reflection for a defined angle of incidence range,
- wherein the holographic arrangement comprises at least one reflection hologram that reflects light waves radiated onto the holographic arrangement via the optical element, and
- wherein the optical element comprises an input coupling device comprising at least one prism and serving to input couple light waves into the wavefront manipulator.
