Abstract:
The analysis of dependence of Rayleigh backscattering intensity statistics of a semiconductor laser in single mode fiber on probe pulse duration and coherence time of the laser source is presented. It is shown that for a given coherence time of the source the probability distribution function of backscattering intensity varies from a function close to exponential decay to Gaussian. Statistics of exponential decay enables to achieve better sensitivity of coherent OTDR with direct signal detection
