Characteristics Of Surface Plasmon Resonance Sensor And Its Application

As an advanced and high-precision sensor, Surface Plasma Wave Sensor (SPWS) can be applied widely. According to the difference of the configuration and substrate of SPWS, two different Surface Plasma Wave sensors exit, such as prism SPWS and optical fiber SPWS, which are studied in the paper.The character of SPWS is presented in terms of the angle of conventional optics in the paper. On the other hand, the microscopic principle of surface plasma resonance is explicated.The device, parameters, factors and the concrete applications of the prism SPWS are studied. In particularly, the relation of the thickness of the metal layer and the surface plasma resonant wavelength and the relation of the incident angle and the surface plasma resonant wavelength based on the theory and experiments.The device, parameters, factors and the concrete applications of the optic fiber SPWS are studied. The silver is plated on the Optic fiber SPWS homogeneously and successfully after the plating device is improved. The relation between the metal thickness and the character of the sensor, the discovery of the distributing optic fiber SPWS, the relation between the surrounding dielectric bulk and the character of sensor; optimization of the length of the sensor tip and temperature characteristic of the sensor are studied in the paper based on the two aspects of theory and experiments.
