Abstract
(EN)
A beam adjusting device (30) comprises: a first light-emitting element that projects a first laser beam L1; a second light-emitting element that projects a second laser beam L2; an optical system (22) that projects, in the same direction, the first laser beam and the second laser beam in an overlapping manner; a first target (32) that obtains first information pertaining to images of the first laser beam and the second laser beam at a first position P1 on the light path of the optical system; a second target (34) that obtains second information pertaining to images of the first laser beam and the second laser beam at a second position P2 on the light path, which is different from the first position; and an adjusting unit (36) that adjusts the configuration of the optical system on the basis of the first information and the second information so that the first laser beam and the second laser beam are aligned with each other.
(FR)
L'invention concerne un dispositif de réglage de faisceau (30) comprenant : un premier élément électroluminescent qui projette un premier faisceau laser L1 ; un second élément électroluminescent qui projette un second faisceau laser L2 ; un système optique (22) qui projette, dans la même direction, le premier faisceau laser et le second faisceau laser de manière chevauchante ; une première cible (32) qui obtient des premières informations concernant des images du premier faisceau laser et du second faisceau laser à une première position P1 sur le trajet de lumière du système optique ; une seconde cible (34) qui obtient des secondes informations concernant des images du premier faisceau laser et du second faisceau laser à une seconde position P2 sur le trajet de lumière, qui est différente de la première position ; et une unité de réglage (36) qui ajuste la configuration du système optique sur la base des premières informations et des secondes informations de telle sorte que le premier faisceau laser et le second faisceau laser sont alignés l'un avec l'autre.
(JA)
ビーム調整装置(30)は、第1のレーザビームL1を出射する第1の発光素子と、第2のレーザビームL2を出射する第2の発光素子と、第1のレーザビームと第2のレーザビームとを重ね合わせて同じ方向に照射する光学系(22)と、光学系の光路の第1の位置P1で第1のレーザビームおよび第2のレーザビームの各像に関する第1の情報を取得する第1のターゲット(32)と、光路の第1の位置と異なる第2の位置P2で第1のレーザビームおよび第2のレーザビームの各像に関する第2の情報を取得する第2のターゲット(34)と、第1の情報および第2の情報に基づいて第1のレーザビームと第2のレーザビームとが揃うように、光学系の構成を調整する調整部(36)と、を備える。
