Abstract
A long-range and high-resolution reflectometry is proposed by synthesis of optical coherence function at region beyond the coherence length has been proposed. We discuss and simulate the principle of the reflectometry system. In basic experiments, the reflectivity distributions are successfully measured at the region beyond the coherence length with a spatial resolution of 19 cm and a measurement range of 1 km.
