Abstract

Infrared signal transmission through zirconium glass fiber is used for noncontact temperature measurement. A fiber optic radiometer using a cooled photonic detector was designed and constructed for temperature measurements between 30 degree(s)C and 200 degree(s)C. An acquisition and data processing software allowing calibration, display, and storage of data was developed. In this work we suggest a new approach for signal processing, based on active filters. This method is compared to the synchronous detection technique using a lock-in amplifier. The dependence of the radiometer signal on ambient temperature and detector cooling is presented. The dependence of the radiometer signal on the black-body temperature is given. The radiometer spatial resolution is calculated. Since real time, high-accuracy low- temperature measurement was obtained, we suggest this IR fiber radiometric thermometer may be useful in medical applications.
