Description
図1は第1実施形態を示す構造物変状検出装置の概略正面図、図2は図1に示す構造物変状検出装置の側断面図で、構造物に変状がない状態を示す。図3は図1に示す加振部のパラメトリックスピーカーの構成を示す図、図4は図1に示す構造物変状検出装置の側断面図で、構造物に変状がある状態を示す。図5は図1に示す振動測定部を構成するレーザドップラ振動計の回路図、図6は図1に示す構造物変状検出装置の検出動作の基本的な流れを説明するフローチャートである。
図7は第2実施形態を示す構造物変状検出装置の概略側断面図で、構造物に変状がない状態を示す。図8は第2実施形態を示す構造物変状検出装置の概略側断面図で、構造物に変状がある状態を示す。図9は図7に示す加振部のパラメトリックスピーカーの制御回路図、図10は図7に示す振動測定部の制御回路図、図11は図7に示す構造物変状検出装置のシステム構成を示す回路図、図12は図7に示す構造物変状検出装置のスピーカーの配置構成を説明する図で、変状がない状態を示す。図13は図7に示す構造物変状検出装置のスキャニング動作を説明する図で、変状がある状態を示す。図14は図12のシステムによる構造物変状検出動作の流れを説明するフローチャート。
検出動作の前に、CPU511は、ガルバノスキャナー420のガルバノミラーによって、レーザドップラ振動計820の測定用レーザビームの照射位置を(x5、y7)のホームポジションに移動させ、レーザ部402を発光させる。レーザビームはレンズ408によって、ガルバノスキャナー420のガルバノミラーのミラー面上にフォーカスされ、さらにミラー面で反射し、レンズ430によって、測定ポイントであるコンクリート上にフォーカスされる。この動作によって(x5、y7)の測定ポイントの振動を計測する。
図15は第4実施形態を示す。
