Abstract

In the present invention, an acoustic wave is transmitted to a first surface S1 of an object S having acoustic anisotropy by a transmission unit 11a disposed on the first surface S1. A plurality of acoustic waves propagating through the inside of the object S at different angles are received by a reception unit 11b disposed on the first surface S1 of the object S or a second surface S2 opposing the first surface S1, and thereby a plurality of pieces of reception information are acquired. A plurality of propagation velocity vectors are calculated based on the plurality of pieces of reception information. A propagation wavefront shape model corresponding to the acoustic anisotropy of the object S is determined based on the plurality of propagation velocity vectors. A horizontal propagation velocity parallel to the first surface S1 is calculated based on the propagation wavefront shape model.
