Abstract
A method of performing near-field acoustic holography comprises the following steps. Establishing () acoustic data representing a set of near-field acoustic holography measurements at a first set of positions. Extrapolating () acoustic data using a model-based extrapolation to obtain extrapolated acoustic data relating to a plurality of positions outside the aperture. Applying () a spatial frequency transform to the padded acoustic data to obtain data in a spatial frequency domain. Propagating () the Fourier transformed acoustic data. Applying () a regularization in a wavenumber domain. Performing () an inverse spatial frequency transform.
