Description
Die vorliegende Erfindung betrifft ein Gerät zur Abbildung von Objekten im freien Raum, ausserhalb eines Gerätegehäuses. Eine solche Abbildung kann rein künstlerischen Zwecken oder aber der Werbung dienen. So ist es beispielsweise möglich, eine Abbildung eines anzubietenden Gegenstandes im Raum ausserhalb eines Schaufensters erscheinen zu lassen. Die Abbildung kann hierbei in den natürlichen Farben des Objektes erfolgen, sofern dasselbe mit weissem Licht beleuchtet wird, oder aber ein fluoreszierendes Objekt kann mittels Schwarzlicht, d.h. mittels UV beleuchtet werden, was eine Abbildung des Objektes ohne dessen Umgebung gestattet. Die Abbildung kann daher in natürlichen Farben oder fluoreszierenden Farben im Gegensatz etwa zur Holographie erfolgen, und es ist eine wirksamere dreidimensionale Abbildung möglich, wobei das Objekt oder die Objekte auch bewegt werden können.
Erfindungsgemäss erfolgt die Abbildung über einen Hohlspiegel. Je nach Wahl der Brennweite des Hohlspiegels und dem Abstand des Objektes vom Hohlspiegel erfolgt eine Abbildung in kleinerem oder grösserem Abstand vom Hohlspiegel bzw. von einer Betrachtungsöffnung des Gerätegehäuses.
Vorzugsweise erfolgt die Abbildung des Objekts über einen Umlenkspiegel, insbesondere einen halbdurchlässigen, ebenen Spiegel der geneigt zwischen der Betrachtungsöffnung des Gerätegehäuses und dem Hohlspiegel angebracht ist. Das abzubildende Objekt kann in diesem Falle eindeutig ausserhalb des Blickfeldes angebracht werden, so dass man von aussen nur das abgebildete nicht aber das wirkliche Objekt sehen kann. Zugleich kann dieser halbdurchlässige Spiegel dazu benutzt werden, andere Objekte, beispielsweise eine Hintergrundskulisse, direkt sichtbar zu machen.
Die Erfindung wird nun anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert.
Das dargestellte Gerät weist ein Gehäuse 1, beispielsweise aus Holz auf, das Beine 2 aufweist und so aufgestellt werden kann, dass sich eine Betrachtungsöffnung 3 mit einer Glasscheibe 4 auf Augenhöhe eines Betrachters befindet. Der Innenraum des Gehäuses 1 ist beispielsweise etwa 1 Meter hoch und 0,4 Meter tief. Hinter der Betrachtungsöffnung 3 befindet sich ein halbdurchlässiger, ebener Spiegel 5, und hinter diesem Spiegel auf der Höhe der Betrachtungsöffnung ein Hohlspiegel 6. Unterhalb des Spiegels 5 befindet sich ein Tisch 7, der mittels Spindeln 8 in der Höhe verstellt werden kann und der dem Aufstellen eines Objekts dient. Beim dargestellten Ausführungsbeispiel befindet sich auf dem Tisch ein Gehäuse 9 mit einem Drehantrieb für einen Drehteller 10 auf welchem sich ein Objekt 11 befindet.
Zur Beleuchtung dieses Objekts dient entweder eine Weisslichtquelle 12 oder aber eine Schwarzlichtquelle bzw. UV-Quelle 13 zur Beleuchtung eines fluoreszierenden Objekts 11. Etwa auf der Höhe des Objekts 11 befindet sich ein Ventilator 14 zur Erzeugung eines Windes in dem das lose angebrachte Objekt 11 natürlich bewegt werden kann. An der Gehäusedecke befindet sich ein Träger 15 an welchem bestimmte Objekte, beispielsweise Hintergrundskulissen 16, angebracht werden können. Eine Beleuchtung 17 dient der Beleuchtung dieser Kulissen. An der Aussenseite ist die Betrachtungsöffnung 3 von einem Bilderrahmen 18 umgeben. Auf dem Drehteller 10 kann ferner eine dem Objekt zugeordnete Vordergrundskulisse 19 angebracht sein.
Die Abbildung des Objekts 11 und der eventuell vorhandenen Vordergrundskulisse 19 erfolgt über den Spiegel 5 und den Hohlspiegel 6 derart, dass ein reelles Bild 11 min des von oben betrachteten Objekts 11 im Raume vor der Betrachtungsöffnung 3 entsteht. Dort entsteht ebenfalls ein reelles Bild 19 min der Vordergrundskulisse 19, die gewissermassen zum Objekt gehört. Über den Spiegel 5 sieht man auch die Hintergrundskulisse 16, die als virtuelles Bild 16 min erscheint. Innerhalb eines bestimmten Bereiches sieht der Betrachter das reelle Bild 11 min im freien Raum ausserhalb des Gerätegehäuses. Die Abbildung ist derart naturgetreu und realistisch, dass man glaubt, das Objekt im Raum vor sich zu haben und es ergreifen zu können.
Besonders realistisch wirkt das Bild, wenn beispielsweise Pflanzen oder nachgebildete Insekten im Winde des Ventilators 14 natürlich bewegt werden oder sonstwie beispielsweise mittels des Drehtellers 10 bewegt werden. Es könnte natürlich auch eine periodische oder zufällige Auf- und Abbewegung des Objekts erfolgen, so dass dasselbe für den Betrachter in variablem Abstand erscheint oder auch gelegentlich verschwindet oder undeutlich wird. Es bestehen somit sehr vielfältige Möglichkeiten zur Erzeugung von Bildern, die sehr natürlich und gegebenenfalls bewegt sind.
The present invention relates to a device for imaging objects in free space outside a device housing. Such an illustration can serve purely artistic purposes or advertising. For example, it is possible to have an image of an object to be offered appear in the room outside of a shop window. The imaging can take place in the natural colors of the object, provided that it is illuminated with white light, or a fluorescent object can be created using black light, i.e. are illuminated by UV, which allows an image of the object without its surroundings. The imaging can therefore take place in natural colors or fluorescent colors, in contrast to holography, and a more effective three-dimensional imaging is possible, whereby the object or objects can also be moved.
According to the invention, the imaging takes place via a concave mirror. Depending on the choice of the focal length of the concave mirror and the distance of the object from the concave mirror, imaging takes place at a smaller or greater distance from the concave mirror or from a viewing opening of the device housing.
The object is preferably imaged via a deflecting mirror, in particular a semitransparent, flat mirror which is mounted at an incline between the viewing opening of the device housing and the concave mirror. In this case, the object to be imaged can be clearly placed outside the field of view, so that from outside you can only see the depicted object but not the real one. At the same time, this semi-transparent mirror can be used to make other objects, such as a background backdrop, directly visible.
The invention will now be explained in more detail with reference to an embodiment shown schematically in the drawing.
The device shown has a housing 1, for example made of wood, which has legs 2 and can be set up such that a viewing opening 3 with a glass pane 4 is at eye level with a viewer. The interior of the housing 1 is, for example, about 1 meter high and 0.4 meters deep. Behind the viewing opening 3 there is a semitransparent, level mirror 5, and behind this mirror at the level of the viewing opening there is a concave mirror 6. Below the mirror 5 there is a table 7 which can be adjusted in height by means of spindles 8 and which can be set up of an object. In the exemplary embodiment shown, there is a housing 9 on the table with a rotary drive for a turntable 10 on which an object 11 is located.
Either a white light source 12 or a black light source or UV source 13 for illuminating a fluorescent object 11 is used to illuminate this object. Approximately at the level of the object 11 is a fan 14 for generating a wind in which the loosely attached object 11 is natural can be moved. On the housing ceiling there is a carrier 15 to which certain objects, for example background backdrops 16, can be attached. Illumination 17 serves to illuminate these backdrops. On the outside, the viewing opening 3 is surrounded by a picture frame 18. A foreground backdrop 19 associated with the object can also be attached to the turntable 10.
Object 11 and any foreground backdrop 19 are imaged via mirror 5 and concave mirror 6 in such a way that a real image 11 min of object 11 viewed from above is created in the space in front of viewing opening 3. A real image 19 min of the foreground backdrop 19, which in a sense belongs to the object, is also created there. The background backdrop 16, which appears as a virtual image 16 minutes, can also be seen via the mirror 5. Within a certain area, the viewer sees the real image for 11 minutes in the free space outside the device housing. The image is so lifelike and realistic that you think you have the object in front of you and can grasp it.
The image appears particularly realistic if, for example, plants or simulated insects are naturally moved in the wind of the fan 14 or are moved in some other way, for example by means of the turntable 10. Of course, a periodic or random up and down movement of the object could also take place, so that the same appears to the viewer at a variable distance or occasionally disappears or becomes indistinct. There are therefore a wide variety of options for generating images that are very natural and, if necessary, moved.
