Abstract

A fiber optic sensor is developed in order to measure film thickness along a curved surface. The technique is non-inva sive, which has large bandwidth and good spatial resolution (150 μ m and 300 μ m). A “ finger ” type surface is used on top of which liquid is poured down in a continuing manner. Film thickness is measured with the fiber optic probe on 2 different locations along the “ finger ” surface. Film thickness of 163 and 79 μ m w as measured near the top and in the middle of the fin surface.
