PROBLEM TO BE SOLVED: To perform imaging of object information over a wide range in a depth direction of an object while suppressing image deterioration.SOLUTION: A measuring apparatus includes: a holding unit for holding the object and a probe including a receiving element for receiving through the holding unit an acoustic wave generated by the object irradiated with light. The light is applied to an object surface held by the holding unit. The probe is arranged such that a direction of a normal to the object surface held by the holding unit is nonparallel to a direction in which the receiving element exhibits its highest reception sensitivity.COPYRIGHT: (C)2012,JPO&INPIT【課題】画像の劣化を抑制しつつ、被検体内の深さ方向において広範囲な被検体情報イメージングを行うための技術を提供する。【解決手段】被検体を保持する保持部と、光を照射された被検体から生じる音響波を保持部を介して受信する受信素子を含む探触子を有し、光は保持部に保持されている被検体表面に照射され、探触子は保持部に保持されている被検体表面の法線の方向と受信素子の受信感度が最も高い方向とが非平行になるように配置される測定装置を用いる。【選択図】図5
