Abstract

L'invention concerne des systèmes et des procédés lidar. Des émetteurs respectifs d'un réseau d'émetteurs émettent des faisceaux dirigés vers des champs de vision par une unité de balayage. Dans un mode de réalisation, l'invention concerne des faisceaux émis dirigés selon un protocole d'éclairage de niveau d'énergie alternatif pour permettre une détection en présence d'éblouissement, le premier faisceau émis par le premier émetteur et ayant un premier niveau d'énergie éclairant une première région de champ de vision, et le second faisceau émis par le second émetteur et ayant un second niveau d'énergie éclairant la seconde région de champ de vision, adjacente à la première région de champ de vision, le premier niveau d'énergie étant inférieur au second niveau d'énergie. Dans un autre mode de réalisation, l'invention concerne également des faisceaux émis dirigés selon un protocole d'éclairage décalé pour permettre une détection en présence d'éblouissement, un premier faisceau émis par le premier émetteur dans une première pluralité de lignes de balayage éclairant une partie de champ de vision à un premier instant, et un second faisceau émis par un second émetteur dans une seconde pluralité de lignes de balayage éclairant une partie de champ de vision à un second instant ultérieur au premier instant. Des détecteurs respectifs d'un réseau de détecteurs détectent des réflexions de faisceaux émis.
