Abstract

PURPOSE:To acknowledge rotational speed and a phase of a turbine by detecting a reflected light from a ceramic plate provided on a rotary shaft by means of an optical detecting means. CONSTITUTION:A turbine blade 2 is driven, and thereby a rotator 5, a ceramic plate 7 and a compressor blade 4 are rotationally driven. A high frequency pulse signal to be converted in an optical signal is sent to optical fibers 81, 82, while a reflected light from the ceramic plate 7 is received thereby. Then a strong reflected light is obtained owing to a good reflection rate when a mirror-processed sector part 71 passes by the fronts of the optical fibers 81, 82, while a weak reflected light is obtained when an irregular reflection face passes by the front thereof. A rotation speed of the turbine blade is computed by detecting the rotations of the strong/weak reflected light. The position of the magnetic pole of the rotator 5 can be sensed by detecting changing points of the reflected light from high intensity to low intensity, and vice versa.
