Title:
MEASUREMENT DEVICE AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/218725
Kind Code:
A1
Abstract:
One measurement device 100 of the present invention comprises: a sound-wave transmission unit 120 that transmits sound waves to a measurement object 10; detection units 130A, 130B that detect electro-magnetic fields which are generated by the measurement object 10 as a result of the sound waves having been emitted from the sound-wave transmission unit, the electro-magnetic fields being from a plurality of mutually different directions or in a plurality of mutually different locations; and an evaluation unit 152 that evaluates characteristics pertaining to the anisotropy of the measurement object 10, on the basis of the results of detection of the electro-magnetic fields by the detection units 130A, 130B.
