我们展示了红外测温可以用来检测嵌入在结构中的光纤的断裂点。在破裂点附近，入射光产生热量，用红外温度计检测。通过这种方法，我们可以实时获得断裂点的位置信息，包括断裂点在实际结构中的准确位置信息。通过检测嵌入碳纤维增强塑料复合结构中的光纤的断裂点，我们通过实验证明了这种方法的实用性。
We show that infrared thermometry can be used to detect a breakage point in an optical fiber embedded in a structure. Around the breakage point, incident light induces heat, which is detected using an infrared thermometer. By this method, we can obtain position information of a breakage point, including accurate information on where it is located in the actual structure, on a real-time basis. We experimentally show the practical usefulness of this method by detecting a breakage point in an optical fiber embedded in a composite structure comprising carbon fiber-reinforced plastics.
