Abstract:
1. Head-mounted display device for generating reconstructions of three-dimensional representations, comprising a frame which resembles a helmet or goggles with at least a front section and two side sections disposed at a distance, where the front section is located in front of eyes and is related to the positions of the eyes, and has a design where there are at least one light source, at least one optical system and at least one light modulator which can be encoded, where the light modulator with a code of a wave front of the three-dimensional representation in the encoding surface is located at the position of a defined observer window in an observer plane or where the light modulator with a code of a hologram of a wave front of the three-dimensional representation in the encoding surface is located in a region close in front of the observer window, seen in the direction of the light propagation, for a transformation of the hologram into the observer window such that its size corresponds at least with a part of the range of movement of an eye pupil of an eye, and where the at least one light modulator is connected to an encoding device in which wave fronts or holograms thereof are computed from the three-dimensional representations for the encoding surfaces, with which the at least one light modulator can be encoded directly, so that if the light modulator is illuminated there are complex wave fronts of the three-dimensional representations in the observer window, and when the light modulator is located in a region close in front of the observer window, the observer window is located in a plane of the light source and the reconstruction of the three-dimensional representation becomes visible in a reconstruction frustum, which stretches between the observer window and the light modulator.
