Abstract: Ultrasonic phased array post-processing imaging techniques make testing and evaluation of defects by using off-line algorithm. Greater defect imaging and characterization abilities have been shown over traditional ultrasonic phased array on-line method. Recently researches on ultrasonic phased array post-processing imaging have been dramatically increased and a series of post-processing imaging methods using full matrix data, like total focusing method, vector total focusing method, wave number algorithm and time reversal imaging with multiple signal classification, have been established and shown significant breakthrough in imaging resolution and minimum detecting size. Starting from full matrix data, the different post-processing imaging techniques are reviewed, and their future development is predicted.

Key words: frequency domain inversion, full matrix data, post-processing imaging, ultrasonic phased array, ultrasonic testing, virtual focusing
