Abstract
PURPOSE:To accurately execute the specification of the trouble point of power source, etc., by providing, at a fixed device side, a rear scattered light measuring system and, at a moving device side, a reflecting part. CONSTITUTION:A pulse signal S5 outputted from a control and monitor part 45 is converted to the light pulse signal of wave length lambda 3 by an electric light converting part 46 and reaches a mirror 56 through an optical fiber 60, an optical fiber reel 51 of a moving device 50, a light mixing dividing wave device 52 and a dummy fiber 55. When the signal is positive at the moving device 50, it is reflected by a reflecting surface 71a of an mirror main body 71, and the power distribution of a rear scattered light can be measured at the control and monitor part 45. When a power source PS of the moving device 50 goes to be in an interrupted condition (an off condition) because of any trouble, since the pulse waveform of a reflecting light does not appear, even the on or off condition of the power source PS can be accurately detected.
