| Abstract: | According to the principle of surface plasmon resonance (SPR) and excitation of SPR, a testing system with optic fiber SPR sensors are home made. Using it, the relationship between refractive index and resonant wavelength of different concentrations from 0% to 70% glycerin solution are measured. Experiments show good repetition and agreement with the theory analysis. Therefore, a method to measure liquid refractive index based on the phenomenon of SPR can be obtained. |

| Keywords: | surface plasmon resonant resonant wavelength refractive index dielectric constant |
