ABSTRACT:
An optical monitoring device includes a reflector, which is mounted on a surface of a rotating member adjacent the periphery to travel in a circular path, and a light source, which creates an input beam which either is directed at a given angle of incidence at a point on the circular path of the reflector or is directed through a waveguide at the point. The device also includes a second waveguide which is arranged on the path of light reflected by the reflector and conducts the reflected light to an opto-electrical transducer which converts the reflected light pulses into electrical pulses which are applied to a source of sound, such as a piezo ceramic plate with a resonator which creates an alarm when a certain frequency is reached.
