Title
(EN) SYSTEMS AND METHODS FOR AN APD ARRAY SOLID-STATE LASER RADAR
(FR) SYSTÈMES ET PROCÉDÉS POUR UN RADAR LASER SOLIDE À SEMI-CONDUCTEUR À RÉSEAU APD
Abstract
(EN)
Methods and systems (30) for detecting and ranging an object (36) may include or be configured to carry out the steps of emitting, by a laser light source, a first beam of light incident on a surface of the object (36), receiving, at an avalanche photodiode (APD) array (38a), a second beam of light reflected from the surface of the object (36); reading, by a readout integrated circuit (ROIC) array (38d), from the APD array (38a); and processing, by the ROIC array (38d), accumulated photocurrent from the APD array (38a) for outputting a signal representative of the object (36) detected by the APD array (38a).
(FR)
Des procédés et des systèmes (30) de détection et de télémétrie d'un objet (36) peuvent comprendre ou être configurés pour exécuter les étapes consistant à émettre, par une source de lumière laser, un premier faisceau de lumière incidente sur une surface de l'objet (36), recevoir, au niveau d'un réseau de photodiodes à avalanche (APD) (38a), un second faisceau de lumière réfléchi à partir de la surface de l'objet (36) ; lire, par un réseau de circuits intégrés de lecture (ROIC), à partir du réseau APD (38a) ; et le traitement, par le réseau ROIC (38d), d'un courant photoélectrique accumulé à partir du réseau APD (38a) pour délivrer un signal représentatif de l'objet (36) détecté par le réseau APD (38a).
