英文摘要	this paper presents a wavelength coded optical timedomain reflectometry based on optical heterodyne technique. in this scheme, the probe and reference optical pulses have different wavelengths. this enables optical heterodyne detection to be used to improve the system performances significantly. we demonstrate a spatial resolution of 2.5 m within a range of 60 km in weak-reflection signal detection and direct observation of brillouin scattering over a long optical fiber, suggesting online fiber sensing possible. the principle of wavelength coding is applicable to other systems like lidar and radar to increase receiver sensitivity and simplify system structure.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-04-13t02:13:57z no. of bitstreams: 1 wavelength coded optical time-domain reflectometry.pdf: 1170382 bytes, checksum: bfa0270888de7e22da597bd2ea9a9c33 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-04-13t02:30:22z (gmt) no. of bitstreams: 1 wavelength coded optical time-domain reflectometry.pdf: 1170382 bytes, checksum: bfa0270888de7e22da597bd2ea9a9c33 (md5); made available in dspace on 2010-04-13t02:30:22z (gmt). no. of bitstreams: 1 wavelength coded optical time-domain reflectometry.pdf: 1170382 bytes, checksum: bfa0270888de7e22da597bd2ea9a9c33 (md5) previous issue date: 2010; 其它
