Abstract: Terahertz (THz) arrays can be used to improve the data acquisition speed considerably in real-time imaging applications. However, the THz array imaging usually suffers from the side-lobe artifacts, which leads to a severe decline in… read more here.

DOI: 10.1109/tuffc.2020.2996076
Abstract: We present a new transmit pulse encoding scheme for ultrafast phased-array imaging called sparse orthogonal diverging wave imaging (SODWI). In SODWI, Hadamard encoding is used to selectively invert transmit pulse phases beamformed with a diverging… read more here.
