Theory and experiment on imaging of walls´ interior structures using diffraction tomography

This paper presents an overview of walls´ interior structure imaging with a novel real-time intra-wall imaging algorithm. The linearization of the inversion scheme and the employment of FFT/IFFT in the imaging formula make the imaging algorithm suitable for on-site applications. An experimental result is presented to show the effectiveness and efficiency of the proposed algorithm for real time intra-wall characterization.
