Title (EN) THREE DIMENSIONAL LIDAR SYSTEM WITH TARGETED FIELD OF VIEW
(FR) LIDAR TRIDIMENSIONNEL AVEC CHAMP DE VISION CIBLÉ
Abstract:
(EN) A plurality of beams of illumination light are emitted from a LIDAR device over a range of angles and scanned about an axis of rotation. The range of angles includes the axis of rotation. Intermediate electronics boards provide mechanical support and electrical connectivity between a rotating electronics board and various elements of a light emission and collection engine. One or more of the optical elements of the collection optics, the illumination optics, or both, is constructed from one or more materials that absorb light outside of a predetermined wavelength range. An overmolded lens is fixedly coupled to one or more of the light detecting elements to collect incoming light over a larger range of angles. A lens element is disposed in the light path between a light emitting element and the illumination optics to flatten the intensity distribution of light emitted from the light emitting element to reduce peak intensity.
(FR) Une pluralité de faisceaux de lumière d'éclairage selon l'invention est émise depuis un dispositif LIDAR sur une plage d'angles et balayés autour d'un axe de rotation. La plage d'angles comprend l'axe de rotation. Des cartes électroniques intermédiaires fournissent un support mécanique et une connectivité électrique entre une carte électronique rotative et divers éléments d'un moteur d'émission et de collecte de lumière. Un ou plusieurs parmi les éléments optiques de l'optique de collecte, l'optique d'éclairage, ou les deux, sont construits à partir d'un ou de plusieurs matériaux qui absorbent la lumière à l'extérieur d'une plage de longueur d'onde prédéfinie. Une lentille surmoulée est accouplée à demeure à un ou plusieurs des éléments de détection de lumière pour collecter la lumière entrante sur une plus grande plage d'angles. Un élément de lentille est disposé dans le trajet de lumière entre un élément électroluminescent et l'optique d'éclairage pour aplatir la distribution d'intensité de la lumière émise par l'élément électroluminescent pour réduire l'intensité de crête.
