Description

Small cracks inside a solid are difficult to detect using a conventional ultrasonic focused transducer because its focal point and radiation direction are fixed. Using a self-focusing array can enhance the ability of crack detection and characterization because the beam steers itself inside a specimen and focuses the ultrasound on the crack, thereby increasing the ultrasonic signal/noise ratio.
