Property measuring device for object to be measured and property measuring method for object to be measured

Abstract

[Problem to be Solved] To provide a property measuring device for measuring a measurement object, which can highly reliably extract an electric signal serving as the measurement object from an electromagnetic field noise or the like generated by an acoustic wave generating source even if the acoustic wave is a continuous wave, while a high spatial resolution is maintained, by using an acoustic wave as a properly measuring means for measuring an object and method thereof. [Means for Solving the Problem] A property measuring devicefor measuring a measurement object of the present invention includes: an acoustic wave emitting portionarranged away from a measurement objectand emitting an amplitude-modulated acoustic wave; a receiverfor receiving an electromagnetic field generated when the acoustic wave is emitted to the measurement object; and a measuring portionfor extracting at least one type of properties selected from a group consisting of an electric property, a magnetic property, an electromechanical property, and a magnetomechanical property of the measurement object, based on at least one measurement selected from a group consisting of measurements of a strength, a phase, and a frequency of the electromagnetic field.
