The technique of optical-time domain reflectometry (OTDR) Is analyzed to determine the effect of an optical phase modulation on light backscattered in an optical fibre. A distributed interferometric sensor arrangement employing this technique has been investigated experimentally, and a satisfactory interrogation of more than one thousand resolution intervals has been demonstrated.
