• 2008:06 Synthetic Aperture Focusing Technique in Ultrasonic Inspection of Coarse Grained Materials

  Experience from the ultrasonic inspection of nuclear power plants has shown that large focused transducers are relatively effective in suppressing grain (structure) noise. Operation of a large focused transducer can be thought of as an integration (coherent summation) of individual beams reflected from the target and received by individual points at the transducer surface. Synthetic aperture...
