<p><P>PROBLEM TO BE SOLVED: To provide a detection method with which a position of a detection target can be accurately grasped, and a non-contact acoustic detection system in which the detection method can be implemented. <P>SOLUTION: The present invention relates to a detection method employing sonic waves. The method includes: irradiating a surface of a body to be irradiated internally including a detection target with sonic waves; measuring a vibration speed at a plurality of measuring positions on that surface; and specifying a position of the detection target from obtained information. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
