Low coherence reflectometer, which is used for measurement of reflective dispersion in optical circuits, suppresses chromatic dispersion effects and thus improves the spatial resolution of measurements

摘要

Reflectometer uses low coherence beams to measure reflective dispersion in an optical circuit (6) comprising a reflection point. The low coherence beams are configured to produce measurement beams (DL) and local beams (KL), such that the measurement beams are injected into a first optical trajectory with a dispersion displacement fiber and the local beams are injected into a second trajectory terminated by a mirror (9). The beams are then combined and subjected to processing and analysis.
