Abstract
3D-Scanner, umfassend einen Lichtsender, einen Lichtempfänger und einen als Lichtablenkvorrichtung um eine Drehachse (D) drehbar ausgebildeten Spiegel (1), dadurch gekennzeichnet, dass der Spiegel (1) als mikromechanischer Spiegel ausgebildet ist.3-D scanner, comprising a light transmitter, a light receiver and a mirror (1) configured as a light deflection device rotatable about an axis of rotation (D), characterized in that the mirror (1) is configured as a micromechanical mirror.
Description
Die Erfindung betrifft einen 3D-Scanner, umfassend einen Lichtsender, einen Lichtempfänger und einen, als Lichtablenkvorrichtung um eine Drehachse drehbar ausgebildeten Spiegel. The invention relates to a 3D scanner, comprising a light emitter, a light receiver and, as a light deflecting device about a rotation axis rotatably formed mirror.
Aus der
Gemäß der
Der Erfindung liegt die Aufgabe zugrunde, einen 3D-Scanner anzugeben, welcher trotz geringer Baugröße einen größtmöglichen Öffnungswinkel erreicht. The invention has for its object to provide a 3D scanner, which achieves the largest possible opening angle despite small size.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Spiegel als mikromechanischer Spiegel ausgebildet ist. Dies hat den Vorteil, dass der 3D-Scanner baulich sehr klein gestaltet werden kann, wobei trotzdem ein größtmöglicher Öffnungswinkel eingestellt werden kann. Vorteilhafterweise wird eine vertikale Auflösung vergrößert. Dadurch wird die Flexibilität des 3D-Scanners erhöht und dessen Herstellungskosten werden gesenkt. According to the invention the object is achieved in that the mirror is designed as a micromechanical mirror. This has the advantage that the 3D scanner can be structurally made very small, while still a maximum opening angle can be adjusted. Advantageously, a vertical resolution is increased. This increases the flexibility of the 3D scanner and reduces its manufacturing costs.
In einer Ausgestaltung sind der Lichtsender und/oder der Lichtempfänger drehbar ausgebildet. Dadurch wird der zu scannende Bereich vergrößert. In one embodiment, the light transmitter and / or the light receiver are rotatably formed. This enlarges the area to be scanned.
In einer Alternative sind der Lichtsender und/oder der Lichtempfänger feststehend ausgebildet. Dies ermöglicht eine besonders robuste Ausgestaltung des 3D-Scanners. In an alternative, the light transmitter and / or the light receiver are designed to be stationary. This allows a particularly robust design of the 3D scanner.
In einer Variante lenkt der mikromechanische Spiegel den vom zu scannenden Objekt reflektierten und dem Lichtempfänger zuleitbaren Lichtstrahl ab. Durch die Verwendung nur eines einzigen mikromechanischen Spiegels als Lichtablenkvorrichtung sowohl für den ausgesandten als auch für den reflektierten Lichtstrahl, verkleinert sich der Aufbau des 3D-Scanners weiter. In one variant, the micromechanical mirror deflects the light beam which is reflected by the object to be scanned and can be directed to the light receiver. By using only a single micromechanical mirror as Lichtablenkvorrichtung both for the emitted and for the reflected light beam, the structure of the 3D scanner continues to shrink.
In einer Weiterbildung ist der mikromechanische Spiegel ein- oder zweiachsig drehbar gelagert. Durch diese Ausbildung erhöht sich die Flexibilität bei der Einstellung des zu scannenden Bereiches. In one development, the micromechanical mirror is rotatably mounted on one or two axes. This design increases the flexibility in setting the area to be scanned.
Je nach vorliegendem Anwendungsfall weist der mikromechanische Spiegel unterschiedliche Durchmesser auf. Depending on the present application, the micromechanical mirror has different diameters.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Eine davon soll anhand der in der Zeichnung dargestellten Figur näher erläutert werden. The invention allows numerous embodiments. One of them will be explained in more detail with reference to the figure shown in the drawing.
