Design a Wind Speed and Direction Sensor Based on Fiber Bragg Grating

In this paper, we proposed a wind speed and direction sensor which based on fiber Bragg grating (FBG). A broadband light source (BBS) was used as the light source. The anemometer consists of two sizes of stainless steel pipe and the coil spring designed to connect a cross-steel frame and the wind-pressed plate. When the wind speed drives the wind-pressed plate, the FBG will change the grating pitch through a special internal structure design to achieve the wind speed and wind direction sensing.
