Abstract

We've analyzed the Fermi high time resolution GRB light curves' autocorrelation function looking for gravitational lens effects. The theoretical amplification-time delay function was applied with a photon count S/N approximation to determine the optimal photon binning. We conclude that during the lens signal search among the Fermi data the usual linearity based techniques (e.g. matched filters, FIR filtering, Bayes blocks, autocorrelation function) are sub-optimal. Only the short and very bright GRBs can be the plausible candidates of these detection techniques.
