Title (EN) OBJECT DETECTION DEVICE OF OPTICAL SCANNING TYPE
(FR) DISPOSITIF DE DÉTECTION D'OBJETS DU TYPE À BALAYAGE OPTIQUE
(JA) 光走査型の対象物検出装置
Abstract:
(EN) Provided is an object detection device of the optical scanning type that is capable of detecting an object that is far away, and ensuring high scanning efficiency. By using a fiber laser FL, it is possible to emit light of comparatively high strength, and it is possible to convert an outgoing beam, which has a circular cross-section and is emitted from the fiber laser FL, into a spot of light having an elongated cross-section by using a shaping lens CY, and as a result, it is possible to effectively detect an imaging subject that is far away, while ensuring high scanning efficiency by minimizing the number of times which a detection range G is to be scanned.
(FR) L'invention concerne un dispositif de détection d'objets du type à balayage optique, capable de détecter un objet éloigné et d'assurer un rendement de balayage élevé. En utilisant un laser FL à fibre, il est possible d'émettre une lumière d'une intensité relativement forte, et il est possible de convertir un faisceau sortant, qui présente une section droite circulaire et est émis à partir du laser FL à fibre, en une tache de lumière présentant une section droite allongée en utilisant une lentille CY de mise en forme, et il est par conséquent possible de détecter efficacement un sujet d'imagerie éloigné, tout en assurant un rendement de balayage élevé en minimisant le nombre de fois où une étendue G de détection doit être balayée.
(JA) 遠方の対象物を検出可能であり、高い走査効率を確保できる光走査型の対象物検出装置を提供する。ファイバーレーザーFLを用いることで、比較的高強度の光を出射することができると共に、ファイバーレーザーFLから出射された円形断面の出射光束を、成形レンズCYによって縦長断面のスポット光に変換できるから、検出範囲Gを走査する回数を少なく抑えて高い走査効率を確保しつつ、遠方の被写体を有効に検出することが可能となる。
