Paper Abstract

We proposed a scheme of optical frequency modulated continuous wave (OFMCW) system based on the polarization diversity heterodyne receiver (PDHR) with a frequency swept distributed feedback (DFB) laser. The adoption of PDHR in OFMCW system successfully reduced the polarization-induced fading and improved the signal to noise ratio (SNR). High-sensitivity OFMCW system is achieved, which has spatial resolution of 1.5 mm for distance of 1.5 km.
