PTAE 4A AE monitor system was developed for monitoring the fatigue crack propagation on aircraft structure. And a study on its practical application was carried out.
It can monitor the crack signal in the concrete structure, for example, bridge, highway, tunnel and building etc., using the embedded optical fiber sensor.
它是用埋入式光纤传感器来监测类似桥梁、高速公路、隧道和房屋建筑等混凝土结构中的开裂信号。
