Method and apparatus for temperature monitoring of a physical structure |
摘要 |
<p>The invention relates to a method for monitoring the condition of a substantially homogenous physical structure (20), wherein the method comprises: measuring temperature of said physical structure by means of an optical fibre sensor (21) for obtaining a set of measured temperatures in a plurality of points of said physical structure, causing a controlled change of temperature in said physical structure, and after that detecting irregularities in said measured temperatures, said irregularities indicating at least one discontinuity in said physical structure. <IMAGE></p> |
