Ultrasonic phased array is a combination of ultrasonic probe chip, arranged by a number of piezoelectric chip according to a certain regular distribution, and then sequentially by a predetermined delay time to stimulate the various wafers, all the ultrasonic waves emitted by the chip to form a whole wavefront, in order to achieve beam displacement, beam deflection and beam focusing and other characteristics, to achieve a variety of testing purposes.

Ultrasonic phased array technology has nearly 20 years of development history. Early mainly used in the medical field. Initially, the complexity of the system, the complexity of the wave propagation in solids, and the high cost of cost make it limited for use in industrial non-destructive testing. However, with the rapid development of electronic technology and computer technology, ultrasonic phased array technology is gradually applied to various industries such as industrial non-destructive testing, boilers, pressure vessels, railways, aerospace, petroleum and petrochemicals, electric power and universities.
