Аннотация
A method of three-dimensional ultrasonic tomography based on multi-view probing with multiple emitters and multiple receivers on a cylindrical surface in a wide frequency band is proposed. Emitters and receivers are placed on a ring that moves along the vertical axis. Signal processing is based on the use of matched filtering and is reduced to the calculation of cyclic convolution along the angle and vertical axis, which makes it possible to implement a fast algorithm for recovering of three-dimensional images. To test the method, an experimental setup was developed consisting of 32 emitters and 64 receivers uniformly placed on a ring with a radius of 205 mm. During the experiments, sounding was carried out in air at frequencies from 38 kHz to 43 kHz. As a result, a three-dimensional object of a complex shape is visualized, which confirms the applicability of the proposed method.
