摘要：

Optical losses ranging over 15 dB are automatically offset (for signal frequencies approximately 1540 to 1553 nm) with an Er-doped fibre amplifier used in a feedback configuration. This technique can recover local optical loss while preserving phase information, and is applicable to scale-factor stabilisation in interferometric fibre sensors.
