Using this technique some advantages are obtained: the ultrasonic system is very simple; it avoids the grating lobes formation, characteristic in conventional SAFT; and subaperture size and focussing lens (to compensate emission-reception) can be adapted dynamically to every image point. The proposed method has been experimentally tested in the inspection of CFRP samples. © 2010 American Institute of Physics.2023-2030engLinear arraySAFTUltrasonic NDETrabalho apresentado em evento10.1063/1.3362366Acesso aberto2-s2.0-779501489162-s2.0-77950148916.pdf64053395108832030000-0003-4201-5617
