Abstract: PURPOSE: A stimulated Brillouin scattering-based optical fiber sensor device using optical frequency modulation is provided to have high spatial resolution and to select a measurement position, thereby measuring the strain or temperature of the measurement position. CONSTITUTION: A stimulated Brillouin scattering-based optical fiber sensor device using optical frequency modulation includes an electro-optical phase modulator (102), a light splitter (104), an electro-optical intensity modulator (106), a delay optical fiber (108), a first optical fiber amplifier (110), a single-sided wave modulator (112), a second optical fiber amplifier (114), a sensing optical fiber (116), an optical detector (120), a data acquisition board (124), and a control unit (126). The electro-optical phase modulator modulates continuous oscillation lights emitted by a light source (100) into continuous oscillation lights having a frequency change of a sine waveform. The light splitter splits the continuous oscillation lights passed through the electro-optical phase modulator into first optical signals and second optical signals. The electro-optical intensity modulator modulates the intensity of the first optical signals split by the light splitter. The delay optical fiber delays passing time of the first optical signals passed through the electro-optical intensity modulator. The first optical fiber amplifier amplifies the first optical signals passed through the delay optical fiber. The single-sided wave modulator downwardly moves frequencies of the second optical signals split by the light splitter.
