摘要
The reflectometer of the invention is intended for analysing guided optical components, an optical fibre, or networks of optical guides. …??The means for analysing the back-scattered response signal comprise:… - means 20 of producing a light-pump wave 21, composed of brief periodic pulses, the frequency of repetition of these pulses being near the frequency of repetition of the probe signal, or near a multiple or sub-multiple of this frequency,… - means 19 ensuring the interaction of the pump wave with the back-scattered response signal 13 in such a way as to carry out the optical sampling of the response signal and the production of a sampled light signal 14, - means of reception 15 and… - an electronic unit 17 recomposing the back-scattered response signal 18. …IMAGE…
