The Design Of Optical Fiber Temperature Sensor Based On Thermal Expansion Mechanism Of Metal |
| |
Abstract: | The design of optical fiber temperature sensor based on thermal expansion mechanism of metal is introduced. Because of the thermal expansion feature of metal, the loss of optical fiber bound to the metalwork would be changed . While the optical output power of light is invariable, the optical power received by the detector is modulated by temperature, After the optoelectronic switching and signal processing, the measured-temperature is transferred to the electric signal . Taking the optical fiber as the transmission method and the light as the signal carrier, the sensor has the advantages such as stronger anti-interference capability, more stable and reliable measurement results and higher sensitivity etc. |
