Abstract
The invention relates to an optical system for generating a two- or three-dimensional image, the system comprising: a projection apparatus for optically transmitting image information to at least one user; an eye detection apparatus; and an imaging apparatus for imaging the image information of the projection device, so that the user can perceive said image information. The imaging apparatus comprises at least one optical hologram set, at least one of which sets is designed to be angle-amplifying. Using the projection apparatus, at least one virtual optical point is generated, or a plurality of optical points are generated such that they form at least one optical wave front, each virtual optical point being generated by the superposition of at least two coherent light waves in the region of the at least one angle-amplifying optical hologram set, and the at least one optical hologram set is used to image the at least one virtual point or the at least one optical wavefront onto the eyes of the at least one user. The respective movements of the eyes of the at least one user can be detected by the eye detection apparatus and the latter cooperates with the projection apparatus in such a…
