摘要： A low coherent reflectometer uses low coherent beams for measurement of refletance and refleting positions with respect to a measured optical circuit which includes a reflecting point. The low coherent beams are branched to produce measurement beams (DL) and local beams (KL), so that the measurement beams are introduced into a first optical path, which includes a dispersion shifted fiber, towards the measured optical circuit, while the local beams are introduced into a second optical path which includes a spatial optical path terminated by a reflecting mirror. Refleted measurement beams (RL) and reflected local beams are combined together to produce combined beams, which are subjected to processing and analysis.
