Figure 2From: A new method for measuring wetness of flowing steam based on surface plasmon resonanceSchematic and results of the measurement system with top surface partially immersed in water. (a) Schematic of top view of the measurement system. (b) SPR spectra under various immersion percentages. (c) Dependence of the reflectivity at 693 nm against the immersed area: (dots) experimental data and (line) linear fit.Back to article page
