“…5 These phase-based algorithms are not sensitive to the dispersion nature of Lamb waves. 6 Some researchers synthesized different imaging algorithms to obtain defect imaging results with high resolution, such as combining the TFM and SCF, [7][8][9] and the TFM and multi-apodization polarity technique. 10 The elliptic imaging algorithm 11,12 and hyperbolic imaging algorithm 13 are two typical algorithms based on sparse arrays where the distance between adjacent transducers is larger than the largest wavelength of waves.…”

“…It is known that ultrasonic transducer arrays are able to provide increased flexibility and superior performance. Therefore, Liu et al (2016) localized the damage in plate-like structures by analysis conducted on the signals recorded by transducer array. In addition, Yan and Rose (2007) applied the linear phased piezoelectric transducer array to composite aircraft panels, which accordingly suppressed the influence of anisotropy by employing a modified delay-and-sum algorithm.…”

“…In most applications, guided Lamb wave is generated and received by piezoelectric transducer (PZT) glued to the test specimen [6,7,8]. Many PZT sensor and Lamb wave-based damage monitoring methods have been studied, including the delay-and-sum [9,10,11], time reversal focusing–based [12,13,14], probability-based diagnostic [15,16,17], ultrasonic phased array [18,19,20], and multiple signal classification [21,22,23,24] imaging methods. In these methods, damage is identified and characterized by analyzing the characteristics of the damage monitoring signal in the time and/or frequency domain after the damage affects the Lamb wave scattering, such as time–of–flight, amplitude and energy.…”
