Abstract
A method for estimating a wetted length of a solid surface includes sensing intensity of light reflected from a gas-liquid interface on the solid surface. A waveguide faces the gas-liquid interface and a diffused light is propagated to the gas-liquid interface through the waveguide. At least one optical receiver is positioned on a side of the waveguide to receive light reflected from the gas-liquid interface.
