Abstract
An examination of the effects of spatial sampling and image noise on the precision with which the centroids of different geometric shapes can be determined is presented. The concentric ring fiducial-a bull´s-eye pattern-is identified as having desirable qualities of high location precision and rotational invariance. The performance of the concentric fiducial, as a function of diameter, number of rings. and ring spacing, has been tested, and these results are shown
