本文讨论了一种新的方法来监测海洋升力面状况，通过使用阵列的光纤布拉格光栅（FBG）为基础的声学传感器在船舶舵。这些光学传感器阵列的结果，然后交叉比较与传统的压电（PZT）传感器。然而，光学传感器方法的成功概念验证评估首先是通过使用集成到玻璃板中的级联FBG来进行的，监测对在不同位置掉落标准金属球的响应。所获得的数据进行了比较，并与传统的PZT传感器的声学传感器进行比较，使用三角测量，以确定激励源（超声波发生器）的位置。所获得的结果验证了基于FBG的传感器的优异性能，由于这些不同的传感器类型之间的良好协议。这为下一阶段扩大其他海洋结构的FBG传感器阵列提供了信心，早期识别气蚀的开始是提高海洋船舶运行可靠性和维护计划的重要优先事项。
This paper discusses a novel approach to monitor marine lifting surface conditions through using arrays of Fibre Bragg Grating (FBG)-based acoustic sensors in a marine rudder. Results from these optical sensor arrays are then cross compared with those from conventional piezoelectric (PZT) sensors. A successful proof-of-concept evaluation of the optical sensor approach was, however, first undertaken by using cascaded FBGs integrated into a glass plate, monitoring the response to dropping a standard metal ball at different locations. Data obtained were compared with colocated conventional PZT sensors acoustic sensors for comparison using triangulation to determine the location of the excitation source (a sonotrode). The results obtained verify the excellent performance of the FBG-based sensors due to the excellent agreement between these different sensor types. This gives confidence to the next-stage to scale-up the FBG sensor arrays for other marine structures, with early identification of the initiation of cavitation erosion an important priority for better operational reliability and scheduling of maintenance of marine vessels.
