An apparatus for measuring local humidity with optical fibers is applied to the measurement of local humidity change near a wetted surface, which is suddenly turned downward at the upper side of a dry air chamber. Measured values of water-vapor concentration and its change agree approximately with analytical ones. For more accurate measurement and a more compact construction, a double beams system was constructed and calibration tests and local humidity measurement were carried out. It was clarified that the calibration results are the same as with the one beam system, which has the same optical path length, and that this system is also applicable to measurement of local humidity change with double accuracy.
