Abstract:
(EN) The present invention relates to a laser scanner (100), comprising a transmission path (102) and a reception path (104) which is at least in some regions is spatially separated from the transmission path (102). The transmission path (102) and the reception path (104) here impinge on an angularly dispalceable mirror element (110) of the laser scanner (100) from different angles (106, 108). An angular position (112) of the mirror element (110) defines a scan angle (114) of a laser light (116) of the laser scanner (100) in the transmission path (102). The angular position (112) compensates for an incident angle (118) of a reflection (120) of the laser beam (116) in the reception path (104).
(FR) La présente invention concerne un scanner laser (100) qui comprend une trajectoire d’émission (102) et une trajectoire de réception (104) séparée spatialement de la trajectoire d'émission (102) au moins dans certaines zones. La trajectoire d'émission (102) et la trajectoire de réception (104) frappent suivant des angles (106, 108) différents un élément miroir (110), pouvant effectuer un déplacement angulaire, du scanner laser (100). Une position angulaire (112) de l'élément miroir (110) définit dans la trajectoire d'émission (102) un angle de balayage (114) d'une lumière laser (116) du scanner laser (100). Dans la trajectoire de réception (104), la position angulaire (112) compense un angle d'incidence (118) d'une réflexion (120) de la lumière laser (116).
(DE) Die vorliegende Erfindung betrifft einen Laserscanner (100), der einen Sendepfad (102) und einen von dem Sendepfad (102) zumindest bereichsweise räumlich getrennten Empfangspfad (104) aufweist. Der Sendepfad (102) und der Empfangspfad (104) treffen dabei aus unterschiedlichen Winkeln (106, 108) auf ein winkelbewegliches Spiegelelement (110) des Laserscanners (100). Eine Winkelstellung (112) des Spiegelelements (110) definiert im Sendepfad (102) einen Scanwinkel (114) eines Laserlichts (116) des Laserscanners (100). Im Empfangspfad (104) kompensiert die Winkelstellung (112) einen Einfallswinkel (118) einer Reflexion (120) des Laserlichts (116).
