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 similar to 200 mu m and sensitivity down to similar to -80 dB with line length of up to 9 meters.
