    • PURPOSE: A method of measuring the temperature distribution using a Raman OTDR temperature sensor is provided to enhance a signal to noise ratio at a measuring end by increasing the intensity of Raman rear scattered light. CONSTITUTION: A method of measuring the temperature distribution using a Raman OTDR temperature sensor is as follows. The width and duty ratio of an input pulse light for measuring temperature distribution are established(S201). Light source at an input end is modulated to be a given width of pulse light and enters optical fiber through a light circulating unit(S202). The intensity of the Raman rear scattered light is differentiated and slope is calculated(S203). The temperature and temperature change section of the optical fiber depending on distance based on the calculated slope are measured(S204).

    • A temperature measuring apparatus and a method for measuring temperature are provided to improve the precision of the temperature measurement by producing interference position based on signals filtered by frequency and producing corresponding interference position from the result. A temperature measuring apparatus(100) comprises a light source(110), a first splitter(120), a reference light reflective unit(140), an optical path length changing unit(150), a second splitter(121), a first detector(160), a second optical detector(161), and a temperature production unit. The first splitter divides the light into measurement light and reference light. The optical path length changing unit diversifies the optical path length of the reflected reference light. The second splitter divides the reflection reference light into the first reflection reference light and the second reflection reference light. The first detector measures interference between the reflection measurement light and the first reflection reference light. The second optical detector measures the intensity of the second reflection reference light. The temperature production unit produces the interference position and the temperature of the temperature measurement object from the result produced by subtracting the output signal of the second optical detector from the output signal of the first detector.
