The Influence of the Speed and Angle of the Laser Speed Sensor on Its Stability

In this work, the influence of the shaft rotation speed, the distance from the optical sensor to the rotor, and the tilt angles of the laser optical sensor on its stability in operation were investigated. The illuminator was a low-divergence and high-power laser module. The technique of obtaining the input and output signals of the laser speed sensor is described. Various tilt angles of the laser optical sensor were investigated at 15°, 30°, 60°, 90°, 120°, 150°, 165°. Through research, the maximum distance from the optical sensor to the rotor with its stable operation was found, which is 350 cm.
