METHOD FOR MEASURING TEMPERATURE DISTRIBUTION OF OBJECT, AND SENSOR UNIT

摘要

The present invention relates to a measuring method and a sensor unit of measuring temperature distribution of an object by using an optical fiber sensing technology of BOCDA system. In the measuring method, an optical fiber that functions as a BOCDA-type optical fiber sensor is disposed two-dimensionally or three-dimensionally with respect to a predetermined measurement region of the object, and thereby the temperature distribution of the object can be measured at a high speed and a high accuracy, in the predetermined measurement region configuring a surface or space where the optical fiber is disposed.
