摘要: Optical frequency domain reflectometry (OFDR) measurements with 60 dB dynamics on the 1.55 /spl mu/m Rayleigh backscattering signal 2 cm spatial resolution and 10 m maximum range are presented. A sensitivity of -152.5 is demonstrated, representing highest reported to date using OFDR technique. This level was achieved <3 min total acquisition time.
