Three-dimensional imaging system based on Fourier transform synthetic aperture focusing technique

Study of beamforming techniques for ultrasound imaging in nondestructive testing

“…This scheme was determined to have better potential for carrying out the mathematical operations numerically, and served as a means to predict incomplete data produced by limited data apertures and limited frequency bandwidths. A 3-D imaging system based on Fourier transform SAFT was further investigated by Mayer and his colleagues in 1989 [14]. Here the algorithm was implemented to provide a high resolution graphics to display a 3-D reconstruction volume.…”

Light Water Reactor Sustainability Non-Destrustive Evaluation for Concrete Research and Development Roadmap

“…Especially in combination with the SAFT (Synthetic Aperture Focusing Technique) algorithm [17] [18], this method is highly suitable for imaging of the inner volume of a structure and detection of volumetric or planar reflectors.…”

Influence of Filtering Techniques on Holographic Images

“…L-SAFT is a technique developed by FHG-IzfP. Theoretical investigations [8] show that it is essentially equivalent to the algorithm of Broad Band Holography. This can also be seen from a direct comparison of Figs.…”
