Abstract
【解決手段】植物の画像を捕捉しかつ植物を位置決めするように構成される三次元イメージャ1203A〜Cと、捕捉される植物画像を基礎として、必要な植物と不要な植物とを区別するように構成される画像プロセッサと、不要な植物を損傷するに足るパワーを有するレーザビームを放射するように構成される少なくとも1つのレーザデバイスと、少なくとも1つのレーザビームを不要な植物へと方向づけるように構成される誘導システムと、三次元イメージャ、レーザデバイスおよび誘導システムを支持するように構成されるシャーシとから構成される。
【選択図】図12
Description
「ダイオードバー」は、広域エミッタの一次元アレイを含むハイパワー半導体レーザ(レーザダイオード)、あるいは10〜50本の狭ストライプを含むサブアレイを指し、
「高速」軸は、(楕円形断面の出力を有する)レーザダイオードからの、最も大きい発散角および最も低い有効屈折率を有する楕円軸に沿った放射を指し、他の楕円軸を正常軸または「遅速」軸と呼び、
「加速度計」、「ガルボミラー」または「ガルボスキャナ」は電子信号に応答するデバイスを指し、加速度計は、力(例えば、重力)を検知してこれを電子信号に変換することができ、ミラーは、電子信号を基礎として反射角を変更することができ、かつスキャナは、レーザビームによる掃引を大きい角度に渡って方向づけることができ、
「マイクロ加速器」、「マイクロミラー」または「マイクロスキャナ」は、「ガルボ加速度計」、「ガルボミラー」または「ガルボスキャナ」と交換可能式に使用されるMEMS集積センサまたはアクチュエータデバイスであって、典型的には、遙かに小さいフォームファクタおよびより高いレベルの集積化を有し、
「レイリーレンジ」は、ビームの伝搬方向に沿った、そのくびれまたは最も狭いビーム断面からこの断面積が倍増する場所までの距離を指す。
x=b(x1+x2)/2・(x1−x2)
y=b(y1+y2)/2・(x1−x2)
z=b・f/(x1−x2)
