Patent number: 8467132Abstract: 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.Type: GrantFiled: February 25, 2010Date of Patent: June 18, 2013Assignee: Carl Zeiss AGInventors: Hans-Juergen Dobschal, Guenter Rudolph, Karsten Lindig

Patent number: 8456744Abstract: 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.Type: GrantFiled: February 25, 2010Date of Patent: June 4, 2013Assignee: Carl Zeiss AGInventors: Hans-Juergen Dobschal, Guenter Rudolph, Karsten Lindig
