Paper Abstract

In an experiment in which two or more photoevents arriving at the same pixel are considered as a single count, a one-pixel-size central hole appears in the autocorrelation estimate. This hole is a source of error when high resolution techniques based on the autocorrelation function measurement are applied to image or signal recovery.

This contribution analyze a previously proposed experimental method to evaluate t1e autocorrelation central hole using an image detector and an auxiliary photomultiplier. The analysis allows to optimize the technique performance by selecting appropriate values for the beam splitter transmission coefficient.
