(EN) MOUNTING CONFIGURATIONS FOR OPTOELECTRONIC COMPONENTS IN LIDAR SYSTEMS
(FR) CONFIGURATIONS DE MONTAGE POUR COMPOSANTS OPTOÉLECTRONIQUES DANS DES SYSTÈMES LIDAR
Abstract
(EN)
A LiDAR system includes a first optical lens, and one or more first optoelectronic packages spaced apart from the first optical lens along the optical axis of the first optical lens. Each respective first optoelectronic package includes a first plurality of optoelectronic components positioned on the respective first optoelectronic package such that a surface of each respective optoelectronic component lies substantially on the first surface of best focus. The LiDAR system further includes a second optical lens, and one or more second optoelectronic packages spaced apart from the second optical lens along the optical axis of the second optical lens. Each respective second optoelectronic package includes a second plurality of optoelectronic components positioned on the respective second optoelectronic package such that a surface of each respective optoelectronic component lies substantially on the second surface of best focus.

L'invention concerne un système LiDAR comprenant une première lentille optique, et un ou plusieurs premiers boîtiers optoélectroniques espacés de la première lentille optique le long de l'axe optique de celle-ci. Chaque premier boîtier optoélectronique respectif comprend une première pluralité de composants optoélectroniques positionnés sur le premier boîtier optoélectronique respectif de telle sorte qu'une surface de chaque composant optoélectronique respectif se trouve sensiblement sur la première surface de la meilleure focalisation. Le système LiDAR comprend en outre une seconde lentille optique, et un ou plusieurs seconds boîtiers optoélectroniques espacés de la seconde lentille optique le long de l'axe optique de celle-ci. Chaque second boîtier optoélectronique respectif comprend une seconde pluralité de composants optoélectroniques positionnés sur le second boîtier optoélectronique respectif de telle sorte qu'une surface de chaque composant optoélectronique respectif se trouve sensiblement sur la seconde surface de la meilleure focalisation.
