摘要:
A method of measuring a property of an object (23) with acoustically induced electromagnetic waves comprises the steps of: irradiating (25) a measurable object with acoustic waves and measuring electromagnetic waves (27) generated from the measurable object to determine any one of properties of the object, including its electrical, magnetic and electromagnetic mechanical properties, from any one or a combination of strength, phase and frequency characteristics of the electromagnetic waves. The acoustic waves with which the measurable object is irradiated are in the form of acoustic wave pulses (26), in which case the electromagnetic waves are measured of time dependence of their intensity detected subsequent to irradiation with said acoustic wave pulses to determine a relaxation characteristic (43) of a property value for charged particles which said measurable object possesses.
