Abstract
(DE)
LIDAR-Sensor (100) zur optischen Erfassung eines Sichtfeldes (106) aufweisend wenigstens eine Sendeeinheit (101) zur Aussendung von Primärlicht (104) in das Sichtfeld (106); und wenigstens eine Empfangseinheit (110) zum Empfangen von Sekundärlicht (109), das im Sichtfeld (106) von einem Objekt (107) reflektiert wurde; wobei die Empfangseinheit (110) eine Detektoreinheit (113) mit wenigstens einem Detektorelement (114) und eine Detektoroptik (112) mit einem nicht-linearen optischen Element (201) aufweist. Das nicht-lineare optische Element (201) ist hierbei dazu ausgebildet, die Frequenz des empfangenen Sekundärlichts (109) zu verdoppeln und frequenzverdoppeltes Sekundärlicht (111) auf die Detektoreinheit (113) zu richten.
(EN)
The invention relates to a LIDAR sensor (100) for optically capturing a field of view (106), comprising: at least one transmitting unit (101) for emitting primary light (104) into the field of view (106); and at least one receiving unit (110) for receiving secondary light (109), which was reflected in the field of view (106) by an object (107). The receiving unit (110) comprises: a detector unit (113), which has at least one detector element (114); and a detector optical unit (112), which has a non-linear optical element (201). The non-linear optical element (201) is designed to double the frequency of the received secondary light (109) and to direct frequency-doubled secondary light (111) at the detector unit (113).

L'invention concerne un capteur LIDAR (100) pour la détection optique d'un champ visuel (106), présentant au moins une unité d'émission (101) pour émettre de la lumière primaire (104) dans le champ visuel (106); et au moins une unité de réception (110) pour recevoir de la lumière secondaire (109) qui a été réfléchie dans le champ visuel (106) par un objet (107); l'unité de réception (110) présentant une unité de détection (113) pourvue d'au moins un élément de détection (114), et une optique de détection (112) pourvu d'un élément optique non linéaire (201). L'élément optique non linéaire (201) est conçu pour doubler la fréquence de la lumière secondaire reçue (109) et pour diriger la lumière secondaire (111) à fréquence doublée sur l'unité de détection (113).
