Laser induced 2D phased array for composite material inspection

激光感应相控阵（LIPAs）与传统的压电超声阵列相比，具有非接触、无耦合剂的特性以及在检测过程中元件位置不固定时改变阵列几何形状的能力等优点。本研究将利用模拟数据设计用于复合材料缺陷检测的二维LIPA，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作为二维阵列在改进复合材料缺陷检测和表征方面的适用性。

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.
