Figure 2 Refractive index Measurement results of ethanol–water mixtures obtained using the SPR holographic microscope.  Demodulated small RI (at 632.8 nm) changes over time for ethanol–water mixtures with mass concentrations of 7.5, 8.0, and 8.4 wt%. The inset shows the schematic of the Ag–Au bilayer SPR excitation configuration.
