METHOD FOR MEASURING TEMPERATURE DISTRIBUTION OF OBJECT, AND SENSOR UNIT

摘要

Provided are a measuring method for measuring temperature distribution of an object by using an optical fiber sensing technology of a BOCDA system, and a sensor unit. In the measuring method, an optical fiber which functions as an optical fiber sensor of the BOCDA system is arranged two-dimensionally or three-dimensionally in a prescribed measuring region of the object. Thus, temperature distribution of the object can be quickly and highly accurately measured in the prescribed measuring region which configures a surface or a space wherein the optical fiber is arranged.
