Abstract
A system () for fiber-optic reflectometry includes an optical source (), a beat detection module () and a processor (). The optical source is configured to generate an optical interrogation signal that is transmitted into an optical fiber (). The beat detection module is configured to receive from the optical fiber an optical backscattering signal in response to the optical interrogation signal, and to mix the optical backscattering signal with a reference replica of the optical interrogation signal using In-phase/Quadrature (I/Q) mixing, so as to produce a complex beat signal having In-phase (I) and Quadrature (Q) components. The processor is configured to sense one or more events affecting the optical fiber by analyzing the I and Q components of the complex beat signal.
