Abstract
The concept of signal processing for 3D acoustical imaging should be based on holographic techniques or simplifications of these techniques. The holographic approach is attractive both from the point of flexibility and implementation. With appropriate hardware a real-time 3D-imaging system can only be practically realized by parallel processing on orthogonal vectors in the spatial Fourier domain. Techniques, commonly used in seismic exploration, are proposed for manipulating the acoustic measurements in Fourier oriented domains.
Ultimate image quality is given by the maximum number of elements which can be gathered in one 2D-linear transducer array.
