Title:
FLUORESCENCE TEMPERATURE SENSOR AND METHOD FOR DETERMINING FAILURE OF SAME
Document Type and Number:
WIPO Patent Application WO/2010/106919
Kind Code:
A1
Abstract:
Provided are a fluorescence temperature sensor, which can demarcate and identify a failure portion when the fluorescence temperature sensor has the failure, and a method for determining the failure.
The fluorescence temperature sensor (1) is provided with: a fluorescent body (4) which emits fluorescence by means of excitation light; a light projecting section (10) which turns on a light source and projects the excitation light to the fluorescent body (4); a light receiving section (12) which receives the fluorescence from the fluorescent body (4); an optical fiber (5) which guides light between the light projecting section (10) and the fluorescent body (4) and between the light receiving section (12) and the fluorescent body; and a processing section (13) which calculates the temperature of a subject to be measured, based on the quantity of light received by the light receiving section (12). The processing section (13) determines the failure of the fluorescence temperature sensor (1) by comparing the quantity of light received by the light receiving section (12) with a threshold previously set corresponding to the operation status of the light projecting section (10).
