摘要： The invention relates to a projection system comprising a projector (10) and a deflection mirror (11), in which the projected image, after following a direction of projection along a principal axis of projection (5), strikes the deflection mirror (11) which is mounted such that it can be moved in two spatial directions.he mirror surface of said mirror deflects a projected light bundle (22) at an elevation angle and an azimuth angle onto a projection surface (9) positioned on the ground (4). The image is projected from the direction of a zenith (2) at an angle β which is less than 60° in relation to a vertical starting from said zenith (2). The deflection mirror (11) is positioned on the ground (4). The projected light bundle (22) can be deflected towards the projection surface (9) such that an image (6) can be created on said projection surface (9) and displaced on same.

摘要： Das Planetarium enthält eine Kuppel (4), eine Bildwand (5) und einen Zuschauerraum (15) unter der Kuppel (4) und eine Informations-Videoanlage (2), die in mindestens einem Ausschnit (6) angeordnet ist, der im unteren Teil der Seitenfläche der Kuppel (4) ausgeführt ist, und eine in Fenstertechnik ausgeführte Bildwand aufweist. Die Fenster (7) der in 'Fenstertechnik ausgeführten Bildwand sind dreh- 'und/oder verschiebbar in mindestens einer Richtung ausgeführt und bilden ein sich im Raum änderndes volumetrisches Mehrebenen-Bildwandsystem. Die Informationen treffen auf eine beliebige Kombination der Fenster (7) von mindestens einem Projektor (17) auf.

摘要： A projection apparatus for generating a moving star field and a cloud-like effect comprises a means for generating a cloud-like effect using at least one non¬ coherent light source, a means for generating a moving star field using at least one coherent light source and a means for regulating and supplying electric power. The means for generating cloud-like effect using at least one non-coherent light source comprises at least one pair of condenser lenses and an interferential filter wheel rotated by a motor, disposed between at least one pair of condenser lenses. The means for generating the moving star field using a coherent light source comprises a grating wheel rotated by a motor and a diffractive optical element disposed between the at least one coherent light source and the grating wheel.

摘要： Ce planétaire est remarquable en ce qu'il comprend une sphère (5) constituée de deux demi-sphères (1-2) distinctes dont les plans diamétraux sont opposés et en regard et définissant entre elles un espace (e) variable selon les besoins, lesdites demi-sphères étant solidarisées entre elles par des moyens de liaison situés dans leur partie centrale, ceux-ci étant associés à un moyen (6) disposé entre les deux demi-sphères ayant au moins une fonction de fixation par rapport à une structure porteuse, ledites demi-sphères étant par leurs moyens porteurs assujetties à un positionnement variable dans les 3 axes géométriques, sans qu'il y ait d'interférence de ladite structure lors de la projection du flux sur la voûte ; lesdites demi-sphères étant agencées avec des moyens autorisant la projection d'un flux lumineux sur la voûte de la salle d'un planétarium, et des moyens (11-T) représentant certains corps célestes.

摘要： A spherical world globe (4') with geographic features imprinted on its surface rotates on an axis (2') through the poles. The sphere is not large enough to carry legible details of all areas. Greater details are stored in a memory (12') such as a compact disc. An indicator (8') on the sphere is positionable north and south or the sphere is positionable relative to a fixed indicator to position the indicator along a north/south meridian . A sensor (11') senses the north/south position of the indicator and sends a signal to a control circuit (19) connected to the memory. Another sensor (10') connected to the rotation of the sphere sends an east/west signal to the control circuit. Using the two signals, the circuit finds the area corresponding to the area selected on the sphere in the memory and displays it on a display in greater detail than is visible on the sphere.

摘要： A device fro projection onto a dome has several projectors (50, 51, 54, 56) for representing images on an at least partly spherical projection surface (52), each projector (50, 51, 54, 56) being arranged so that it illuminates one or more partial surfaces (56, 58) on the projection surface (52) with partial images. A light source (12) and a deflection device (40) are provided for one or more of the projectors (51, 54, 56), by means of which a beam of light (10) emitted from the light source (12) to represent the image can be guided over the part to be illuminated. The deflection device (40) for the one or more projectors (51, 54, 56) is designed as a grid device with which the beam of light can be guided in several lines with several picture elements over the partial surface (56, 58) to be illuminated, and the light source (12) is connected to an intensity control (64), which allows individual pixels to be illuminated with suitable luminance to represent the partial image (56, 58).
