Resumo

We present a stochastic investigation of Talbot temporal effect under random variations of the localization of Gaussian pulses comprising a train. We analyze the variance of the detected train, noticing that, after its pass through a dispersive line, localized variations are smoothed along the basic time slot of the train. Finally, we calculate the spectral power of the detected signal, showing the presence of spectral windows that produce a coherent filtering mechanism on the initial broadband noise.
