ABSTRACT:
A method and reflectometer used to analyze guided optical components, optical fibers or optical guide networks by time reflectometry in a time sphere. The method comprises steps of creating a light probe signal, feeding the light probe signals into the guide connected to the system, creating a pumped signal, obtaining a backscattered response signal from the system, sampling the backscattered response signal by interacting the pump signal therewith to produce a sampled signal, and receiving the sampled signal with a photodetector, which is blind to the pump signal and the backscattered response signal and will recompose the backscattered response signal from the sampled signal. The reflectometer has a unit for forming the light probe signal, a light flow separator device for injecting the probe signal into a guide and extracting a backscattered response signal therefrom, a unit for analyzing the backscattered response signal which includes a unit for producing a light pump signal, a unit causing interaction of the pump signal with the backscattered response signal to provide an optical sampling of the response signal and produce a sample light signal, a photodetector receiving the sampled light signal and insensitive to the pump signal and to the backscattered response signal, an electrical unit for processing and storing the output of the photodetector and for recomposing the backscattered response signal therefrom.
