Abstract :
Time-correlated photon counting with solid state detectors is of considerable interest for high resolution optical time-domain reflectometry (OTDR). Up to now long measurement times were required. A new approach is described, yielding measurement times 50 times shorter and dynamic range enhanced by approximately=20 dB.
