Abstract: A display device including a holding device that can be placed on the head of a user, an image generating module fixed to the holding device and generating an image, and a multifunction glass that is fixed to the holding device and has a coupling in area and a coupling out area. The image produced is coupled into the multifunction glass via the coupling in area, guided in the multifunction glass to the coupling in area, and coupled out via the coupling out area, in such a way that the user can perceive the coupled out image superimposed on the surroundings when the holding device is placed on the head of the user. The coupling out area has a Fresnel structure which receives light from the coupling-in-area via a folded beam path and couples the image out of the multifunction optical element. The coupling out element has an imaging property.

Abstract: A display device includes a holding device that can be placed on the head of a user. An image-generating module and an imaging lens system can be secured on the holding device. The latter includes a spectacle lens with a curved front and a curved back. It projects the image generated when the holding device is placed on the head such that the user can perceive it superimposed on the surroundings. Light from the image-generating module is coupled into an optical channel in the spectacle lens. It is conducted in the optical channel to an exit section and coupled via the exit section out of the spectacle lens. The optical channel includes in the region of the front and back a Fresnel structure with a plurality of facets on which the light conducted in the optical channel is reflected, and which are aligned parallel to one another.

Abstract: A display device including a holding device that can be placed on the head of a user, an image generating module fixed to the holding device and generating an image, and a multifunction glass that is fixed to the holding device and has a coupling in area and a coupling out area. The image produced is coupled into the multifunction glass via the coupling in area, guided in the multifunction glass to the coupling in area, and extracted via the coupling out area, in such a way that the user can perceive the coupled out image superimposed on the surroundings when the holding device is placed on the head of the user. The coupling in area has a Fresnel structure causing a folding of the beam path when the image is injected into the multifunction glass, said structure having an imaging property.

Abstract: A beam combiner for combining a first beam cluster with a second beam cluster that is not parallel to the first, to form a common beam cluster. The beam combiner includes a transparent body for the first beam cluster, which has a superimposition region that is encountered by the first beam cluster as it passes through the body. The superimposition region is split into a first section and a second section. Only the first section formed from interspaced reflective and/or refractive deflection elements causes a deflection of the second beam cluster by reflection and/or refraction, such that the first beam cluster forms the common beam cluster with the deflected second beam cluster once it has left the body.

Abstract: The invention relates to a device for superimposing an image in the beam path of an aiming optics, having an at least partially transparent optical support element which is arranged in the beam path of the aiming optics and has at least one diffractive optical coupling element and at least one diffractive optical decoupling element, the at least one diffractive optical coupling element leading light of the image to be superimposed, which light is incident on said coupling element and is to be coupled in, through the optical support element to the at least one diffractive optical decoupling element for the purpose of superimposition with the beam path. The image to be superimposed is imaged into the beam path of the aiming optics by the at least one diffractive optical coupling element and the least one diffractive optical decoupling element.
