Ultrasonic testing for crack detection involves sending high-frequency sound waves into a material. When the sound waves encounter a crack, some of the energy reflects back.

Therefore, crack detection in concrete structures plays a crucial role in damage assessment and post-care of the structure. The main concrete crack detection methods include ultrasonic method ...

Recently, interest in automatic crack detection on concrete structure images for non-destructive inspection has been increasing. In general, there are various noises such as irregularly illuminated ...

Laser scanning has several advantages over other methods of crack detection, such as visual inspection, ultrasound, or infrared thermography. It is fast and non-contact, so it can cover large ...

The detection of a defect that may have been missed by a metal-loss tool (such as stress corrosion cracking) is certainly beneficial to the operator; however, in many cases, crack-detection tools may ...

Micro crack detection. Intego has come up with the Antares system for micro crack detection for wafer, ... The concept is not disturbed by metallization and the natural grain structure.

Defect detection requirements on the order of 10 defective parts per million (DPPM) are driving improvements in inspection ...
