Abstract: A method and the resulting apparatus for implementing a unique multiple beam fringe sensor that is adapted to be interfaced with a low cost, compact fiber optic transmission system in order to provide an accurate digital representation of a physical parameter (e. g. temperature) of a remote sample. The sensor is fabricated so as to include a Fabrey-Perot gap (2) formed between the ends of two mated optical (10, 12) fibers. By examining the optical characteristics of light that is transmitted through the Fabrey-Perot sensor gap (2), an indication of gap width can be ascertained. Accordingly, a change in Fabrey-Perot sensor gap width is related to a change in the particular physical parameter to be measured.

Abstract: The concentration of deuterium relative to hydrogen in a hydrofluorocarbon is increased by contacting the hydrofluorocarbon, in the presence of an alkali metal amide, with an amine having a concentration of deuterium that is greater than that which provides equilibrium with the hydrofluorocarbon. In a preferred embodiment, a compound enriched in deuterium is produced by first exposing trifluoromethane to infrared laser radiation to selectively cause a chemical reaction involving deuterium-containing molecules. The deuterium-depleted trifluoromethane is deuterium replenished by exchange with an amine, and the compound enriched in deuterium is converted to heavy water. Heavy water is useful in certain types of nuclear reactors.
