Abstract: front page image
(EN)A laser radar device (100) installed in a vehicle, comprising: first laser irradiation units (R1-R4) for generating a measuring laser beam (L2) using a laser beam (L0) emitted by a laser source (21), and irradiating a predetermined range ahead in the direction of travel; and second laser irradiation units (R5, R6) for generating a measuring laser beam (L2) using the laser beam (L0) emitted by the laser source (21), and irradiating a predetermined range on the road surface. A beam spread angle (α) of measuring laser beams (L25, L26) generated by the second laser irradiation units (R5, R6) as seen from the side of the vehicle is greater than a beam spread angle (θ) of measuring laser beams (L21-L24) generated by the first laser irradiation units (R1-R4) as seen from the side of the vehicle.
(FR)Selon l'invention, un dispositif radar laser (100) installé dans un véhicule comprend des premiers modules de rayonnement laser (R1-R4) pour générer un faisceau laser de mesure (L2) au moyen d'un faisceau laser (L0) émis par une source laser (21), et faire rayonner une portée prédéterminée au-delà de la direction du trajet; et des deuxièmes modules de rayonnement laser (R5, R6) pour générer un faisceau laser de mesure (L2) au moyen du faisceau laser (L0) émis par la source laser (21), et faire rayonner une portée prédéterminée sur la surface de la route. Un angle de propagation de faisceau (α) des faisceaux laser de mesure (R5, R6) tel que perçu du côté du véhicule est supérieur à un angle de propagation de faisceau (θ) des faisceaux laser de mesure (L21-L24) générés par les premiers modules de rayonnement laser (R1-R4) tels que perçus du côté du véhicule.
(JA) 車両に搭載されレーザレーダ装置(100)は、レーザ源(21)が放射するレーザビーム(L0)を用いて測定用レーザビーム(L2)を生成し、進行方向前方の所定範囲を照射する第一レーザ照射部(R1~R4)と、レーザ源(21)が放射するレーザビーム(L0)を用いて測定用レーザビーム(L2)を生成し、路面上の所定範囲を照射する第二レーザ照射部(R5、R6)とを備え、第二レーザ照射部(R5、R6)が生成する測定用レーザビーム(L25、L26)の車両側方から見たビーム拡がり角(α)は、第一レーザ照射部(R1~R4)が生成する測定用レーザビーム(L21~L24)の車両側方から見たビーム拡がり角(θ)よりも大きい。
