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.
