| Abstract: | Pulsed carried ESPI combined with computerized tomography (CT) technique have been used to evaluate the three dimension wave front and pressure field distributions of diffraction field of acoustic wave through different aperture masks. Experiments are accomplished by using an electrical discharge between two electrodes as the sound source. Experimental results are given and the property of CT reconstruction are discussed in condition of noise projections. |
