IPC: G01M11/00
Filed: 1989-03-27
Abstract: PURPOSE:To make it possible to detect a broken point at high resolution without deterioration in S/N of backward Rayleigh scattering light by adjusting each pattern of optical pulses and exciting optical pulses into a desired pattern. CONSTITUTION:Optical pulses and exciting optical pulses generated in a laser light source 1a are adjusted with a light pulse adjuster 3a and emitted so that the difference in optical frequencies is made to agree with the shifting amount of the optical frequency of a Brilluoin light that is generated in an optical fiber to be measured FB. The optical pulses and the exciting optical pulses are inputted into one end surface of the optical fiber to be measured, and backward Rayleigh scattering light is generated. At the approximately same time, a Brilluoin light amplified state is induced in the optical fiber to be measured by the exciting pulses. Thus, the backward Rayleigh scattering light is emitted from one end surface of the optical fiber to be measured. Then, the backward Rayleigh scattering light is split with an optical coupler 7 and inputted into a photodetector 8. The intensity of the backward Rayleigh scattering light is detected. The detected signal is inputted into a signal processor 9, and the intensity of the backward Rayleigh scattering light is computed.
