Abstract:
    The present invention relates to optical measurement instrument, and aims at providing one kind of thin film type optical fiber temperature sensor with high temp sensitivity and high reliability and its temperature sensing method. Structurally, the optical fiber temperature sensor includes one optical fiber with one light signal incoming end face and one light signal outgoing end face, and the light signal outgoing end face is coated with one optical medium film, which has reflectivity changing with temperature. The thin film type optical fiber temperature sensor operates on that the refractivity and thus the reflectivity or the transmissivity of the optical medium film vary with temperature.
