Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist es abtastende Laserabstandssensoren nach dem Lichtlaufzeitverfahren mit schwingenden oder umlaufenden Lasern inklusive deren Projektionsoptiken zu ermöglichen wobei in der schwingenden oder umlaufenden Einheit nur wenige einfache Bauteile nötig sind. Damit ergeben sich niedrige Bauteilekosten und eine einfache und kostengünstige Justage und Fertigung. Darüber hinaus soll die Projektion des Lasers über den Drehwinkel der Abtastung in bezug auf die Drehachse konstant bleiben. Außerdem sollen sowohl axial als auch radial hohe Toleranzen zulässig sein. Diese Aufgabe wird mit einem Laserabstandssensor gemäß Anspruch 1 oder 2 gelöst.task The invention is scanning laser distance sensors according to the light transit time method with oscillating or circulating lasers including their projection optics to enable being in the oscillating or orbiting unit only a few simple Components needed are. This results in low component costs and a simple and inexpensive Adjustment and production. Furthermore should the projection of the laser over the angle of rotation of the scan with respect to the axis of rotation constant stay. Furthermore Both axially and radially high tolerances should be allowed. This object is achieved with a laser distance sensor according to claim 1 or 2 solved.
