Title
(DE) LIDAR-SENSORSYSTEM MIT VERBESSERTER OBERFLÄCHENGÜTE
(EN) LIDAR SENSOR SYSTEM HAVING IMPROVED SURFACE QUALITY
(FR) SYSTÈME DE DÉTECTION LIDAR À QUALITÉ DE SURFACE AMÉLIORÉE
Abstract
(DE)
Ein Sensor-System umfasst eine LiDAR-Einheit mit einem Sender für Laserlicht mit einer Wellenlänge von 800 nm bis 1600 nm und einem Empfänger für Licht mit einer Wellenlänge von 800 nm bis 1600 nm und eine Abdeckung, welche so angeordnet ist, dass von der LiDAR-Einheit ausgesandtes und von ihr empfangenes IR-Licht durch die Abdeckung hindurch tritt. Die Abdeckung weist eine Schicht eines thermoplastischen Materials auf, wobei das thermoplastische Material ein transparentes thermoplastisches Polymer und einen Monoester einer Monocarbonsäure mit ≥ 15 C-Atomen mit Glycerin oder mit einem Monoalkohol mit ≥ 15 C-Atomen enthält. Weiterhin ist das thermoplastische Material frei von Mono-, Di-, Tri- und Tetraestern der Stearinsäure mit Pentaerythritol.
(EN)
A sensor system comprises a LiDAR unit having a transmitter for laser light having a wavelength of 800 nm to 1600 nm and a receiver for light having a wavelength of 800 nm to 1600 nm, and a cover arranged such that IR light emitted by the LiDAR unit and received by the latter pass through the cover. The cover comprises a layer of a thermoplastic material, wherein the thermoplastic material contains a transparent thermoplastic polymer and a monoester of a monocarboxylic acid having ≥15 C atoms with glycerol or with a monoalcohol having ≥15 C atoms. Furthermore, the thermoplastic material is free of mono-, di-, tri- and tetraesters of stearic acid with pentaerythritol.

L'invention concerne un système de détection comprenant une unité LiDAR comprenant un émetteur pour de la lumière laser ayant une longueur d'onde de 800 nm à 1600 nm et un récepteur pour de la lumière ayant une longueur d'onde de 800 nm à 1600 nm, et un cache qui est disposé de sorte que la lumière IR émise et reçue par l'unité LiDAR traverse le cache. Le cache présente une couche en matière thermoplastique, la matière thermoplastique contenant un polymère thermoplastique transparent et un monoester d'un acide monocarboxylique ayant ≥ 15 atomes de C avec de la glycérine ou un monoalcool ayant ≥ 15 atomes de C. Par ailleurs, la matière thermoplastique est dépourvue de mono-, di, tri- et tétraesters d'acide stéarinique avec du pentaérythritol.
