摘要:
A measuring method and apparatus in which a measurable object (23) is irradiated with acoustic waves to measure a change in property value of charged particles in the object from electromagnetic waves induced thereby. A part (2) of the measurable object irradiated with an acoustic focused beam (1) is in a charge distribution state in which positive charged particles (3) are greater in number in the part (2) where electromagnetic waves induced by positive charged particles (3) are not canceled by those induced by negative charged particles (4) and where net electromagnetic waves (6) are induced. Since a change in concentration of positive charged particles (3) and/or negative charged particles (4) changes the intensity of electromagnetic waves (6), it is possible to know such a change in concentration of the charged particles from a change in intensity of electromagnetic waves (6).

PROBLEM TO BE SOLVED: To provide a method and apparatus for measuring characteristics of an object with an acoustically induced electromagnetic wave capable of irradiating electromagnetic wave with acoustic vibration and being applicable to every object including a human body.SOLUTION: A method and apparatus for measuring characteristics of an object with acoustically induced electromagnetic wave measures a change in the characteristic value or the like of charged particles in an object from an electromagnetic wave induced by irradiating an object to be measured with an acoustic wave. The portion (2) of the object to be measured which is irradiated with an acoustic wave focus beam (1) is in a charge distributed state in which many positive charged particles (3) are present, and thus the electromagnetic waves induced by the positive charged particles (3) and negative charged particles (4) do not completely negate each other to produce an actual electromagnetic wave (6). When the concentration of the positive charged particles (3) and/or the negative charged particles (4) changes, the strength of the electromagnetic wave (6) changes, thus allowing the concentration change in the charged particles to be detected from the strength change in the electromagnetic wave (6).
