Abstract
(DE)
Offenbart wird eine Vorrichtung und ein Verfahren zum Kompensieren von mindestens einer Nichtlinearität, die durch eine Bewegung einer Lichtablenkeinrichtung, insbesondere durch eine Schwingung von mindestens einem Ablenkspiegel in einem Laserprojektionssystem, entsteht, wobei die Vorrichtung ein Linsensystem mit mindestens einer Linse aufweist, das eine Verzeichnung bereitstellt, die die Nichtlinearitäten kompensiert, sowie ein Projektionssystem, insbesondere ein Laserprojektionssystem, mit einer solchen Vorrichtung.
(EN)
The invention discloses an apparatus and a method for compensating for at least one non-linearity which arises as a result of movement of a light deflection device, particularly as a result of oscillation of at least one deflection mirror in a laser projection system, wherein the apparatus has a lens system having at least one lens which provides a distortion which compensates for the non-linearities, and also a projection system, particularly a laser projection system, having such an apparatus.
(FR)
L'invention concerne un dispositif et un procédé pour compenser au moins un défaut de linéarité qui est provoqué par un mouvement d'un dispositif de déviation de lumière, notamment par une oscillation d'au moins un miroir de déviation dans un système de projection à laser. Selon l'invention, le dispositif présente un système de lentilles comprenant au moins une lentille fournissant une distorsion d'image qui compense le défaut de linéarité, ainsi qu'un système de projection, notamment un système de projection à laser, équipé d'un tel dispositif.
