In order to eradicate the optoelectronic device's measurement error caused by the variation of temperature calibration coefficient,the temperature sensing system's working principle and structure and demodulation process were presented. The experimental results show that the real-time calibration technology can eradicate the above-said measurement error and can ensure the accuracy in temperature demodulation. The sensing system's accuracy can reach ± 0. 05℃.
