| Abstract: | The intensity-type liquid’s refraction index measuring system based on the principle of surface plasmon resonance was assembled.The software with simply operative interface to control the hardware was programmed by LabVIEW.The accuracy of the system was confirmed by the good agreement of the experimental measured and theoretical calculated resonance angles of pure water and pure ethanol,respectively.And the refractive indices of several mixtures of water and ethanol with different concentrations were obtained by this system. |
