  • Method and apparatus for defect detection in composite structures
    Patent number: 9494562
    Abstract: Methods and apparatus for non-destructive testing of a composite structure utilizing sonic or ultrasonic waves. In response to a wideband chirp wave sonic excitation signal transmitted from a probe to the composite structure, a probe signal received is correlated with a library of predetermined probe signals and a graphical representation of defects detected is generated. The graphical representation provides detailed information on defect type, defect location and defect shape.
    Type: Grant
    Filed: May 27, 2011
    Date of Patent: November 15, 2016
    Assignee: Agency for Science, Technology and Research
    Inventors: Wei Lin, Lay Siong Goh, Lye Seng Wong, Heng Kiat Jonathan Hey, Ricky Riyadi Chan, Roman Britner
