Abstract
Sternenlaserprojektor
zur dynamischen, farblichen Abbildung des Sternenhimmels, dadurch gekennzeichnet,
dass
der vom Laserprojektor erzeugte Laserstrahl entsprechend dem Aufbau
der eingereichten Skizzen mittels einer Spektralfolie spektral oder
Diffraktiven (DOE) (1). zerlegt wird und derart einzelne Punkte
generiert werden.
Die Spektralfolie ist wie ein Gitter aufgebaut
und beugt die von der Lichtquelle kommenden Lichtstrahlen in waagerechter,
senkrechter und diagonaler Richtung.
Diese ermöglicht durch
ein Spektral, Diffraktiv (DOE's) (1) eine Zerlegung.
DOEs basieren
auf dem Prinzip der Lichtbeugung an periodischen Mikrostrukturen.
In
der eine realistische abbildung eines Sternenhimmes eingearbeitet
wird.
Die mW-Stärke
des Lasers (2) ergibt sich durch das Anfertigen der Oberflächenstrukturierung.
Diffractiven
(DOE) (1) und der Errechnung der Anzahl der Punkte, der einzelne
Strahl die aus dem Diffractiven (DOE) (1) tritt, darf den Wert von
1 mW nicht überschreiten.Star laser projector for the dynamic, color illustration of the starry sky, characterized
that the laser beam generated by the laser projector according to the structure of the submitted sketches by means of a spectral film spectral or diffractive (DOE) (1). disassembled and thus individual points are generated.
The spectral film is constructed like a grid and bends the light rays coming from the light source in horizontal, vertical and diagonal direction.
This enables a decomposition by means of a spectral, diffractive (DOE) (1).
DOEs are based on the principle of light diffraction on periodic microstructures.
In which a realistic illustration of a starry sky is incorporated.
The mW-strength of the laser (2) results from the preparation of the surface structuring.
Diffractivities (DOE) (1) and the calculation of the number of points, the single ray that emerges from the diffractive (DOE) (1), must not exceed the value of 1 mW.
Description
Künstliche Sternenhimmel an Decken oder Wänden werden nach herkömmlicher Technik mittels Leuchtdioden (LED) und Fiberadern und Fibergeneratoren erzeugt. Nach einen anderen Ansatz auch mittels Leuchtdioden (LED) und einem Stanzset, bei der die Nachthimmelkuppel schlicht über eine Lampe gelegt wird. Dabei ist der erzeugt Sternenhimmel stets statisch.artificial Starry sky on ceilings or walls become after conventional Technology using light emitting diodes (LED) and fiber adapters and fiber generators generated. After another approach also by means of light emitting diodes (LED) and a punching set, in which the night sky dome simply over a Lamp is placed. The generated starry sky is always static.
Der im Schutzanspruch angegebenen Erfindung liegt der Gedanke zugrunde mittels eines Laserprojektors das veränderliche und dynamische Abbild eines Sternenhimmels zu projizieren.Of the in protection claim specified invention is based on the idea using a laser projector, the variable and dynamic image to project a starry sky.
Bei
dem Aufbau des Sternenlaserprojektors wird ein Laser
Auf der Spektralfolie ist ein dünnes Gitter, das die von der Lichtquelle kommenden Lichtstrahlen in waagerechter, senkrechter und diagonaler Richtung beugt. Die verschiedenen Spektralanteile werden dabei unterschiedlich stark gebeugt. Beim Blick durch das Spektral liegen die blauen Enden des Spektrums der Lichtquelle am nächsten, die roten am weitesten von ihr entfernt. Die Spektralfolie zerlegt das Licht in seine Farbanteile.On the spectral film is a thin one Grid, which illuminates the light rays coming from the light source horizontally, vertical and diagonal direction bends. The different spectral components are diffracted differently. When looking through the Spectral the blue ends of the spectrum of the light source lie on next the red furthest away from her. The spectral film breaks this up Light in its color components.
Durch die mehrfache Verwendung und Positionierung der Folien kann die Anzahl der erzeugten Punkte verdoppelt werden. Daher ist die Anzahl der Punkte von der Anzahl der aufeinander liegenden Folien abhängig. Die Position der Punkte ist von der Drehung der einzelnen Folien abhängig. Auf diese Weise lassen sich beliebig viele Variationen des Sternenhimmels projizieren.By the multiple use and positioning of the slides can the Number of generated points to be doubled. Therefore, the number is depending on the number of superimposed slides. The Position of the dots depends on the rotation of the individual slides. On this way you can choose any number of variations of the starry sky project.
Mit der Erfindung ist es möglich den Nachthimmel mit einer bisher nicht erreichten Authentizität und Wirkungskraft abzubilden. Dabei ist das System außerordentlich flexibel und lässt sich an jede beliebige Projektionsfläche anpassen.With The invention is possible the night sky with a previously unattained authenticity and effectiveness map. The system is extremely flexible and let yourself to any projection surface to adjust.
Der Aufbau des Sternenlaserprojektors wird durch nachfolgende Skizzen belegt.Of the Construction of the star laser projector is through subsequent sketches busy.
