Abstract: A device for precisely aligning a projection module relative to a projection surface. The device includes a bracket and a front. The bracket is designed to support the projection module. The front is designed to support the projection surface. The device further includes a compensating element for precisely aligning the projection module relative to the projection surface. The compensating element produces a firmly bonded connection between the bracket and the front or between the bracket and the projection module. A method for producing the device is also described.

Abstract: An optical system for a virtual retinal scan display. The system includes: an image source providing image content as image data; an image-processing device; a projector unit for generating at least one light beam, and having a controllable deflecting device for the at least one light beam for the scanning projection of the image content; a diverting unit, onto which the image content is projected, equipped to direct the projected image content onto an eye of a user; an optical segmentation element using which the image content is projectable via different imaging paths onto at least one projection region of the diverting unit, at least individual imaging paths being controllable individually; and an optical replication component equipped to direct the projected image content, replicated and spatially offset, onto the eye of the user, so that a plurality of mutually spatially offset exit pupils having the image content is produced.

Abstract: An optical system for a virtual retinal scan display. The optical system includes an image source which supplies image data, an image processing device for the image data, a projector unit having a light source modulatable in time for generating a light beam, and an actuable refraction device for the light beam for the scanning projection of the image content, a deflection unit onto which the image content is able to be projected and which is designed to guide the projected image content onto an eye of a user, and an adaptive optical element for modifying a beam divergence, which is situated in the optical path between the light source and the deflection unit. The adaptive optical element is able to be actuated so that the beam divergence of the light beam is variable as a function of the angle of incidence of the light beam on the deflection unit.
