Paper Abstract

A novel fiber-optic anemometer based on a distributed Bragg reflector (DBR) fiber laser is reported in this paper. We design a fiber laser pressure sensing setup and a Venturi tube is designed for wind speed measurement. This fiber optic anemometer overcomes the drawbacks of the existing wind sensors with its unique advantages, such as immunity to electromagnetic interference, compact structure, remote detection, multiplexing capability. The measuring range of the anemometer is 8m/s~40m/s, the sensitivity is about 0.3m/s, and the short term repeatability can up to 0.35%. Experimental results reveal that the sensitivity is impacted by power of pump laser which could be further improved. This anemometer has high sensitivity and possibility for multiplexing application on a single fiber.
