The aim of the PhD study is to use laser ultrasonics for remote ultrasonic imaging, addressing the current technological limitations of conventional ultrasonic transducers. The technique uses lasers to generate and detect ultrasound and will have minimum impact on structures, will be electrically neutral and could be applied remotely, even in extreme environments or in places of restricted access, for in-line process monitoring or in-service inspection. The ambition of the PhD project is to translate this capability into safety-critical applications, for example imaging inside aero-engines, or during additive manufacturing, where conventional ultrasonic phased arrays cannot be applied.

该博士研究的目的是利用激光超声进行远程超声成像，解决传统超声换能器当前的技术限制。该技术使用激光产生和检测超声波，对结构的影响最小，呈电中性，并且可以远程应用，即使在极端环境或限制访问的地方，也可以进行在线过程监控或在役检查。该博士项目的目标是将这种能力转化为安全关键型应用，例如航空发动机内部的成像，或传统超声波相控阵无法应用的增材制造过程中的成像。
