Abstract
In this study, we measured an infrared radiation which is transferred by a silver halide optical fiber from a heat source using a radiometer system for low-temperature measurements. To increase the amount of infrared radiation through the silver halide optical fiber and to the pyroelectric sensor, infrared optical devices used were an infrared focusing lens and a collimator. The relationship between the temperatures of a heat source and the measured radiometer signals were determined. The measurable temperature range of a fiber-optic temperature sensor using a pyroelectric sensor was from 298 to 333 K. It is expected that a noncontact low-temperature sensor using an infrared optical fiber can be developed for medical and industrial usages based on the results of this study.
