PURPOSE:To directly grasp the generating condition of cavitation optically by guiding the reflected light by cavitation of the radiated light from an emitting section to a light receiving section to convert it into an electrical signal. CONSTITUTION:When the light emitted from an emitting section 5 to the cavitation 11 is radiated through a light feeding light guide 7 and a rod lens 9, this radiated light 12 is reflected or scattered by the cavitation 11 and is made the reflected light 13, which is guided into a light receiving section 6 through a rod lens 10 and a light receiving light guide 8 at the light receiving side, and the light signal is converted into an electrical output signal at this light receiving section 6, and also this electrical output signal is measured by an electrical instrument such as a voltmeter. |
