摘要: 光纤SPW传感器通过表面等离子体波共振来工作.在SPW传感器表层存在一层电子气,当环境温度升高,电子气的浓度将会增加,且其本身的动能加大,这将导致电子气团的共振频率发生变化.通过实验建立了共振波长和环境温度的关系,并对误差进行了分析,从而进一步扩展了光纤SPW传感器的用途.

Abstract: The working principle of the optic fiber surface plasmon wave (SPW) sensor is based on the resonance of the surface plasmon. A layer of the electronic gas exits on the surface of the sensor. When the environment temperature rises, the density of the electronic gas will increase and the kinetic energy of electronic gas will become stronger. Finally, the resonant frequency of the electronic agglomerate will change. The relationship between the resonant wavelength and the environment temperature is found through experiments and the error is analyzed. the application of the optic fiber SPW sensor is thus broadened.

Key words: temperature, kinetic energy, optic fiber SPW sensor, electronic gas, density
