Projection device and projection varieties

摘要

The invention relates to a projection device (1) for the back projection of images, comprising at least one projector (9) and a rear projection surface (11). In order to further develop such a projection device advantageously, it is proposed that the projection device (1) a three-dimensional projection dome (3), on which the rear projection surface (11) is located, and a far angle projection objective, and in that the projector (9) in the operation of the receptacles by means of the far angle projection lens to the rear projection surface (11) of the projection dome (3) is projected. Furthermore, the invention relates to a system for generating and to the rear projection of round receptacles. A system for the production and rear projection of round receptacles to develop advantageously, it is proposed that the system at least one projection device (1) and at least a 360° of domes - camera comprises. In addition, the invention relates to a process for the rear projection of round receptacles, in particular, of about images or round film images, comprising at least the steps of: providing round receptacles, providing a projection device (1), projecting the round receptacles provided on the projection dome (3) of the rear projection surface (11). Furthermore, the invention relates to a projection dome (3), which comprises, or a coupling member which consists of a coupling member is. In order to further develop such a projection dome advantageous, it is proposed that the coupling member is fabricated from acrylic glass, by means of thermoforming an acrylic-glass sheet in a dome. In addition, the invention relates to a process for the production of a dome projection surface, comprising at least the steps of: providing an acrylic glass plate and reshaping of the acrylic glass plate by means of thermoforming in a dome.
