Description
f1>4×D1の場合、遠距離レーザビーム4が筐体11の開口部エッジに干渉し回折が大きくなり縦横比が増大する。
f1>8×D2の場合、遠近両用レーザ光学装置の筐体11の前方5m付近の近距離レーザビーム3のレーザパタンサイズは比例的に減少する。
Claims (1)
- レーザビームを出射するレーザ光源と、
前記レーザビームを絞るために前記レーザ光源の出射端から指定距離だけ離して前記レーザビームの光軸上に凸部が前記レーザビームの入射側になるように配置され、所定の曲率半径を有すると共に、入射面中央に円形の平面部が形成されるレンズと
を具備し、
前記レンズの前記指定距離を前記曲率半径に基づいて設定される前記レンズの焦点距離と等しくし、
レンズ開口径を前記焦点距離の1/4とし、
前記平面部の直径を前記焦点距離の1/8とすることで、
予め設定されたレーザ強度以上のレーザパタンのサイズが近距離の第1の位置から、遠距離の第2の位置にかけて予め設定された許容範囲内で一定の大きさで維持されることを特徴とする遠近両用レーザ光学装置。
