A photoelectric rotational speed sensor applied to the environment of vibration is designed. The sensor is developed according to the principle of photoelectric conversion to measure the rotational speed of the airplane wheel. The front rotational speed signal is converted to the electrical signal by the sensor, and the rotational speed of the airplane wheel is calculated. This design method could meet the needs of the rotational measurement. The cause of failure of the sensor in the environment of vibration is analyzed, and the structure of the sensor is optimized. The simulation and the experiment show that the sensor can maintain high reliability and stability in the environment of vibration in the aviation system.
