摘要：
A 2-D wind measurement system is designed based on the 2-D position sensitive device (PSD). Laser is used as a light source in the system. The light spot position on the PSD reflects the information of the wind speed and direction. The working principle and features of the PSD and the wind measurement system are introduced. The measurement system is set up and the wind speed and direction as a function of the position of light spot are measured. The experimental results show that the range of wind measurement is 0 to 30 m/s. Without further amplification, the sensitivity of the wind speed is 0.15 mV/(m · s-1), the mean error of the wind direction measurement is less than 7°. The measurement system is of simple structure, easy measurement and small temperature drift. The measurement sensitivity and the measuring range can be improved by selecting suitable wind sensitive rod.
