13.1 Introduction. Phased array principles have been widely used in radar, sonar, seismology, oceanology, and medical imaging.

Where are phased arrays used?

For example, phased arrays are used to detect and image defects including cracks, voids, and pits caused by corrosion. They are used to measure material and coating thickness and to detect changes in material properties. Another common application is to assess the quality of welds and rivets.

What is phased array probe used for?

Phased array is widely used for nondestructive testing (NDT) in several industrial sectors, such as construction, pipelines, and power generation. This method is an advanced NDT method that is used to detect discontinuities i.e. cracks or flaws and thereby determine component quality.
