介绍了一种利用表面等离子体产生具有大温度相关折射率的材料的光学温度传感器的原理。该传感器的设计包括表面等离子体产生在覆盖有氢化非晶硅（a- si:H）的薄（500 a）银膜上。当温度升高40°C时，玻璃/Ag/ A - si:H界面的反射光强度变化因子为3。该设备与用于远程温度传感应用的光纤技术兼容。
The principles of an optical temperature sensor, using surface plasmon generation in a material with a large temperature-dependent refractive index, are presented. The sensor design consists of surface plasmon generation in a thin (500 A) silver film overlaid with hydrogenated amorphous silicon (a-Si:H). A factor of three change in reflected light intensity, from a glass/Ag/a-Si:H interface, is obtained for a 40°C rise in temperature. The device is compatible with fibre optic technology for remote temperature sensing applications.
