Near-field acoustic holography in conical coordinates. [PDF]
The Journal of the Acoustical Society of America, 2009 Near-field acoustical holography (NAH) techniques can be optimized if the method capitalizes on the geometry of the noise source under investigation. Helmholtz-equation least squares method (HELS) uses the solutions of Helmholtz equation in spherical coordinates as basis functions for the pressure field. HELS is an efficient NAH technique if the source

A Mapping Relationship-Based near-Field Acoustic Holography
, 2023 A mapping relationship-based near-field acoustic holography (MRS-based NAH) is a kind of innovative NAH by exploring the mapping relationship between modes on surfaces of the boundary and hologram. Thus, reconstruction is converted to obtain the coefficients of participant modes on holograms. The MRS-based NAH supplies an analytical method to determine

Direct extrapolation in near‐field acoustic holography
Electronics Letters, 2015 The size and shape of a reconstruction surface is the same as a holography surface in conventional near‐field acoustic holography (NAH), which limits the size and shape of the measurement surface. To reduce the measurement points and use any shape of measurement array, the direct extrapolation in NAH based on wave superposition is proposed.
