Abstract

We report a highly sensitive polarization-independent optical low coherence reflectometer (OLCR) which employs orthogonal polarization switching. Fresnel reflection and Rayleigh backscattering distributions from a device under test can be obtained without adjusting the states of polarization (SOP) of the OLCR local oscillator light. The residual variations in the signal against the SOP change mere within 10.45 and /spl plusmn/0,55 dB at 1.5- and 1.3-μm bands, respectively.
