The author reviews the fundamentals of optical reflectometry, including the standard optical time-domain reflectometry (OTDR) measurement. Some novel reflectometry schemes are described, including a spread-spectrum approach to long-range OTDR, as well as new optical frequency-domain reflectometry (O...
