Paper Abstract

The development of a fiber optic interferometer for static temperature sensing in gas or steam flows and in steam turbines is reported. This paper contains informations from the initial motivations to the test procedures of the prototype. A Michelson interferometer single physical arm, combined with an active phase tracking heterodyne detection has been conceived. Tests of the semi-industrial prototype in a supersonic air pipe are described (resolution 0.5 K, dynamic 50 K). The design of an optical probe for steam turbine measurement is reported and an outline of future experiments of the optical system is given.
