Abstract

The paper presents the first experimental results on operation of an optical frequency domain reflectometer (OFDR) based on a self-sweeping fiber laser. Frequency tuning in this laser is performed without actively tunable elements. Its intensity dynamics consists of regular microsecond pulses. The self-sweeping laser has high linearity of frequency tuning, which allows us to measure the reflectograms without additional spectral correction. The OFDR demonstrates capability of operation with spatial sampling of ~ 200 μm and sensitivity down to ~ -80 dB with line length of up to 9 meters.
