Laser induced phased arrays (LIPAs) have several advantages over traditional piezoelectric ultrasound arrays in terms of their non-contact, couplant free nature, and their ability to change array geometry during an inspection as the element positions are not fixed. The proposed research will design a 2D LIPA for inspection of defects in composite materials using simulated data and implement the array design in experiments. The successful outcome of the research will demonstrate the suitability of using LIPA as 2D array in improving defect inspection and characterisation in composite material.

激光诱导相控阵 (LIPA) 与传统压电超声阵列相比具有多种优势，包括非接触式、无耦合剂性质，以及由于元件位置不固定而在检查期间改变阵列几何形状的能力。拟议的研究将设计一个二维 LIPA，用于使用模拟数据检查复合材料中的缺陷，并在实验中实现阵列设计。该研究的成功结果将证明使用 LIPA 作为二维阵列来改进复合材料的缺陷检测和表征的适用性。
