摘要： A device for measuring vibrations of a rotating blade of a gas turbine includes an optical probe that is mounted within a casing of the rotating blade. The probe includes a light projecting and a light receiving optical fiber along with associated focusing lenses and a protective glass. In addition, liquid coolant channels are provided within the probe housing and air coolant channels are provided within the blade casing in order to protect the probe from the hostile environment of the turbine.
