Improving the Spatial Resolution of an OFDR Based on Recirculating Frequency Shifter

Improving the Spatial Resolution of an OFDR Based on Recirculating Frequency Shifter

We demonstrate a novel method for obtaining high spatial resolution optical frequency domain reflectometry (OFDR) utilizing recirculating frequency shifter for broadening the optical frequency sweeping. Twelve times broadened optical frequency sweeping is achieved. We obtain 0.97 cm spatial resoluti...
