| Abstract: | An optical fiber semiconductor temperature sensor based on single-chip system is introduced. The temperature is measured by the relation between the absorbing rate of the light transmitting of GaAs crystal and the temperature. The signal is tested and processed by the single-chip. Experimental results show that the sensor developed is a promising optical fiber temperature sensor and has high accuracy about 0. 2 degree between -50 degree and 150 degree, high stability, high reliability and performance/price rate. The sensor is used in some practical industry applications. |
