Abstract
We have designed a morphological filter in order to calculate the centroid spots of Hartmann patterns. This filter is based on four directional structuring elements. Each element takes into account the general morphology of the spots of the Hartmann pattern. The efficiency of the filter was tested by using a simulated pattern of spots. Finally, we apply this filter to experimental Hartmann patterns obtained for small convex lenses.
