Abstract
Phased array is a phase synthesis imaging technique developed in field of radar, and has been widely used in medical diagnosis using accurate acoustic imaging. Recently it became one of the core nondestructive inspection methods mainly for periodic inspection of nuclear power equipment. Here, we explain the control of the transmission sound field of ultrasonic phased array and also the aperture synthesis method in imaging processing of received signals. In addition, new equipment of SPACE (Subharmonic Phased Array for Crack Evaluation), which is the nonlinear ultrasonic flaw detection technique as the industrial application of Phased Array techniques, will be mentioned.
