Abstract: An optical fiber anemometer based on the Pitot-static tube is reported. The device was fabricated in a 3-D printer, and the pressure difference was assessed by means of a latex rubber diaphragm with a mounted fiber Bragg grating probe, so the membrane deflection is obtained in terms of the fiber curvature. The sensor characteristics were first obtained by the simulation in order to determine the correlation between the Bragg wavelength shifts and the airflow speed. Next, the device was experimentally evaluated in a wind tunnel, allowing for the assessment of a 20-36-m/s dynamic range, with 24.9-pm/(m/s) maximum sensitivity and 0.04-m/s resolution. Finally, the system was tested on the measurement of cyclic airflow speeds for predicting the applied speed according to the calibration curve, yielding reproducible results with an average error of 0.98 m/s, which is comparable to other reported sensors based on more complex designs and interrogation setups
