| 摘要 |
<p>A sensing cable comprising one or more optical fibers, a coating which is provided on the one or more optical fibers, wherein the coating is configured so that pressure applied to the sensing cable, along one or more axes, induces less lateral compression on the one or more optical fibers than pressure applied to the sensing cable along one or more other axes so as to change birefringence in the one or more optical fibers.</p> |
