Three-Dimension Reconstruction of Wave-Front and Pressure Field of Space-Diffraction-Sound-Wave by Computerized Tomography

• The pulsed-carried ESPI (electron speckle photographic interference) and the with computerized tomography (CT) technique were used to evaluate the three-dimensional wavefront and pressure field distribution of diffraction field of acoustic wave through different aperture masks. Experiments were carried out by using an electrical discharge between two electrodes as sound source. The property of CT reconstruction under the conditions of noise projection was discussed
