| Abstract: | This paper discusses the application of an improved medical B-scan linear array probe to industrial NDT. An improved method on the base of synthetic aperture focusing technique (SAFT) is developed, which can form an image with high signal-to-noise ratio (SNR) from narrow-bandwidth signal. The imaging system and the experimental method as well as some experimental results are presented. |
