PURPOSE:To monitor the effective output during the operation of a titled device and to facilitate the maintenance and inspection of an optical waveguide by providing a storage device for the power of the leading end of the optical waveguide, a support system for converting the power of the leading end, a storage device for the leading end converted output and power attenuation rate and a display device. CONSTITUTION:A laser oscillator 3 and an optical waveguide 4 are connected to a power meter 5 respectively via shutters S4, S3. A comparator 7 which compares the voltage corresponding to the output of the leading end of the waveguide and the voltage corresponding to the output of the exit end is connected to a storage circuit 6 which stores the former voltage and further, a servemotor 8 which is driven by the differential voltage thereof is connected, and a potentiometer 9 of which of the contacts are moved by this is provided. Further, an arithmetic circuit 14 which converts the output of the exit end to the output of the leading end of the waveguide provided, and a storage circuit 10 storing the converted output and a display device 11 thereof are connected. |
