PROBLEM TO BE SOLVED: To provide a measuring apparatus that can obtain high resolution while maintaining sensitivity anywhere.SOLUTION: The measuring apparatus includes: an acoustic detecting unit including at least one detector which receives an acoustic wave generated from an object to which light is irradiated and converts the acoustic wave into an electrical signal and a processor which generates image data of the object by using the electrical signal based on the acoustic wave received by the acoustic detecting unit at first and second measurement locations, wherein the acoustic detecting unit is arranged so as to form an overlapped area where effective receiving areas of the detector are overlapped in the first and second measurement locations.COPYRIGHT: (C)2013,JPO&INPIT【課題】 感度を保ちながら高い分解能を場所依存なく得られる測定装置を提供する。【解決手段】 光を照射された被検体から発生する音響波を受信し電気信号に変換する検出器を少なくとも1つ含む音響検出手段と、音響検出手段が第1および第2の測定位置にて受信した音響波に基づく電気信号を用いて被検体の画像データを生成する処理装置を有し、第1および第2の測定位置における前記検出器の有効受信範囲が被検体内で重なる重畳領域を形成するように音響検出手段が配置される測定装置を用いる。【選択図】 図3
