Ultrasonic Tomography Using Sparse Antenna Arrays and Frequency Domain Post-Processing
Source abstract
Abstract
Abstract To date, increasing the speed of producing results in the form of images of defects in test objects remains an urgent problem for industrial ultrasonic tomography using post-processing of matrix antenna arrays data. One of the approaches aimed at solving this problem is the use of sparse matrix AAs. In this paper, we consider the combined application of sparse matrix transducers operating in pitch and catch mode and the post-processing algorithm that is based on the use of calculations in the frequency domain. This algorithm is based on the use of nonuniform fast Fourier transform. The effectiveness of the considered approach is confirmed experimentally.
