Abstract:
(EN) According to the present invention, a LIDAR 1 is provided with; an APD 41 that receives return light Lr which is obtained by reflecting, by a target object, emission light Lo that has been irradiated from a scanning part 55; and a DSP 16. The DSP 16 is provided with: a shot noise estimation unit 77 that estimates, on the basis of an output signal from the APD 41, information on an amount of background light which is obtained by reflecting solar light by the target object and is received by the APD 41; and a voltage control unit 78 which determines an application voltage to be applied to the APD 41 so as to control a gain M of the APD 41, on the basis of the estimated information on the amount of background light.
(FR) La présente invention concerne un LIDAR (1) comprenant : une PDA (41) qui reçoit une lumière de retour (Lr) qui est obtenue par réflexion, par un objet cible, d'une lumière d'émission (Lo) qui a été émise à partir d'une partie de balayage (55); et un processeur de signaux numériques (16). Le processeur de signaux numériques (16) comprend : une unité d'estimation de bruit de grenaille (77) qui estime, sur la base d'un signal de sortie provenant de la PDA (41), des informations sur une quantité de lumière de fond qui est obtenue par réflexion de la lumière solaire par l'objet cible et qui est reçue par la PDA (41); et une unité de réglage de tension électrique (78) qui détermine une tension électrique d'application à appliquer à la PDA (41) de façon à commander un gain M de la PDA (41), sur la base des informations estimées sur la quantité de lumière de fond.
(JA) ライダ1は、走査部55から照射された射出光Loが対象物によって反射された戻り光Lrを受信するAPD41と、DSP16とを備える。DSP16は、APD41からの出力信号に基づいて、太陽光が対象物によって反射されAPD41によって受信される背景光量に関する情報を推定するショット雑音推定部77と、推定された背景光量に関する情報に基づいて、APD41のゲインMを制御するためのAPD41への印加電圧を決定する電圧制御部78とを備える。
