A unified formulation of inverse problems for near-field acoustical holography
Samon Oie (Ono Sokki) EA2007-37
Abstract (in Japanese) (See Japanese page) 
(in English) A unified formulation of inverse problems for near-field acoustical holography is proposed. The formulation is performed with the aid of a weighted least mean square method. It is shown that one obtains various expressions of coefficients in integral equations for the inverse problem by the choice of various weighting operators. In this report, two types of the weighting operators are chosen; one is a spatially diagonal type and the other is a spectrally diagonal type. For the former choice, the kernel of the integral equation is expressed with the aid of the Green’s function for half-space. For the latter choice, the kernel of the integral equation is expressed as an integral form in the spectral domain. A brief discussion on the comparison of our results with the existing publications is given.
