| Abstract: | This paper presents an intelligent fiber optical temperature measuring method. It is based on the Planck radiation law. Temperature measurement by colorimetry is realized by a single-chip microcomputer. A photodiode with low dark current and operational amplifiers with low noise are adopted to accomplish photo-electric transform and pre-amplification. An MCS-51 single-chip microcomputer is used in the signal processing system. The temperature measured is corrected by hardware and software. It is proved that the device has a wide measurement range, quick response, high sensitivity and good adaptability to environment. |
