Adaptive Laser Induced Phased Arrays (ALIPA)

当前无损检测（NDE）面临的许多挑战来自于越来越多地使用先进材料和制造工艺，这些都推动了材料性能的极限。NDE技术需要能够应对极端环境（高温/放射性环境）、受限访问（发动机内部或通过访问端口）和复杂几何形状。为了应对这些挑战，该项目将开发一种新的实时远程超声成像功能，可用于NDE。这一工程挑战将通过引入相控阵超声的概念变化来实现，超越几何、超声频率和模式阵列特性的限制，通过调整阵列以适应被检测结构的需求，从而实时改变场。该项目的长期愿景不仅仅是检查，而是开发一种监测和控制过程参数的方法，适用于聚变反应堆或涡轮发动机等极端环境。该项目的工业重要性通过项目合作伙伴的大量现金和实物贡献来证明。

Many current challenges in Non-Destructive Evaluation (NDE) stem from the increased use of advanced materials and manufacturing processes that push the limits of materials' performance. NDE techniques are required that can cope with extreme environments (high temperature / radioactive environments), restricted access (inside engines or though access ports), and complex geometries. To address these challenges, this project will develop a new capability for real-time, remote ultrasonic imaging that can be used for NDE. This engineering challenge will be achieved by introducing a conceptual change to phased array ultrasonics, beyond the limits of geometrical, ultrasonic frequency and mode array characteristics, by adapting the array to the demands of the inspected structure, on-the-fly, and thus transforming the field. The long-term vision behind this project goes beyond inspection, to develop a method for monitoring and control of in-process parameters, in places of extreme environments such as fusion reactors or turbine engines. The industrial importance of the project is demonstrated by the significant cash and in-kind contributions of the project partners.
