<p><P>PROBLEM TO BE SOLVED: To provide a temperature measuring method which measures the temperature distribution at a place having a plurality of heat sources such as a data center using an optical fiber with favorable precision. <P>SOLUTION: For example, the optical fiber 45 is laid within an opening/closing door 42a of a rack 41. The optical fiber 45 before being introduced into the rack and the optical fiber 45 after being taken out of the rack are wound around the same jig over a length of 1.5m or more, respectively. On the basis of the measured temperature of the winding part 46, the measured temperature within the rack 45 is corrected. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
