The FBG cantilever sensor was used for detection of flow separation. This optical sensor detects a shift of the wavelength to the reflected light corresponding to the amount of strain. We had researched on the sensing of direction to flows. As a next stage, this sensor was installed at trailing edge of a flat plate, and has investigated on the performance of the sensor and the characteristics of the flow separation. As a result, this sensor could catch the changing of the flow direction and the periodic fluctuation to the flow separation.
