Abstract
In this study, we have developed a noncontact temperature sensor using a silver halides infrared optical fiber for medical endoscopic usage. We have measured an infrared radiation which is transferred by a silver halides optical fiber from a heat source using a thermal optical power-meter. Also, the relationship between the temperature of a heat source and the measured optical power is determined. To increase the amount of infrared radiation through the silver halides optical fiber and to the infrared sensing part of a thermal optical power-meter, optical devices such as an infrared focusing lens and a collimator are used. The relationship between the temperature of a heat source and the measured optical power is determined. The measurable temperature range of a fiberoptic temperature sensor using a thermal optical power-meter is from 30 to 70 °C. It is expected that a noncontact temperature sensor using infrared optical fiber can be developed for medical and industrial usages based on the results of this study.
