Riassunto:Title screen
Fourier diffraction theorem can rapidly predict scattering characteristics of scatterers. This paper theoretically proposes orbital angular momentum (OAM) to simplify the reference library in the underwater Fourier diffraction theorem. An acoustic metasurface is designed to replace the traditional phased array, meanwhile the underwater defect detection combining OAM and Fourier diffraction theorem is verified in the simulation. This acoustic metasurface has a high signal-to-noise ratio when used for underwater defect detection. Compared with the traditional underwater defect detection method, the underwater defect detection method proposed in this paper has the advantages of simple structure and no reference pattern library. © 2022 The Japan Society of Applied Physics
