Ultrasonic detection of fabric defects

特許 係属中 Ultrasonic testing (UT) is a family of non-destructive testing techniques based in the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials.
