摘要：

We demonstrate a delayed self-heterodyne interferometer with a recirculating delay, in which loss is partially compensated by an erbium-doped fiber amplifier. A resolution limit of 606 Hz is achieved with an 11 km fiber delay line, as compared to 18.2 kHz for the standard single-pass case. The possible effect of spectral broadening due to amplifier noise is considered and found to have a negligible effect on the system performance.
