Abstract
In an experiment in which two or more photoevents arriving at the same pixel are considered as a single count, a one-pixel-sized central hole appears in the autocorrelation estimate. This hole is a source of error when high-resolution techniques based on the autocorrelation function are applied to image or signal recovery. We present an experimental method with which to evaluate the autocorrelation central hole based on the simultaneous measurement of the total number of counts in the image detector and an auxiliary photomultiplier. The technique is easy to perform and provides high accuracy.
