Adaptive Laser Induced Phased Arrays (ALIPA)

目前无损评价（NDE）中的许多挑战都源于先进材料和制造工艺的使用增加，这些材料和制造工艺推动了材料性能的极限。NDE技术需要能够科普极端环境（高温/放射性环境），限制进入（发动机内部或通过进入端口）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能力，可用于NDE。这一工程挑战将通过引入相控阵超声波的概念变化来实现，超越几何，超声波频率和模式阵列特性的限制，通过使阵列适应被检结构的需求，在飞行中，从而改变场。该项目背后的长期愿景不仅仅是检测，而是开发一种在极端环境下（如聚变反应堆或涡轮机发动机）监测和控制过程参数的方法。项目伙伴提供的大量现金和实物捐助表明了该项目在工业上的重要性。

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.
