Paper Abstract

In order to achieve centimeter scale spatial resolution along an optic fiber, it is necessary to employ optical sources and detectors with responses on a 100 ps time scale. In this paper, the results are described of an investigation into the limiting capability in terms of spatial resolution, return signal strength, and data acquisition time which can be achieved using a photon counting method of detecting the backscatter signals from a distributed sensor based on standard telecommunications fiber. Particular attention is given to the possibility of obtaining 'real time' update rate on the sensor output while maintaining the centimeter-scale resolution capability.
