(a) Refractive index of water versus wavenumber (blue line) and linear fit (dashed red line). (b) OCT peak position versus thickness of water (red circles) and theory (blue line). Also indicated is the displacement in air (green dashed line). (c) FWHM peak width of the OCT signal versus water thickness (red circles) and theory (blue line). Also indicated is the dispersion-free FWHM peak width (green line).
