The performance of image-plane sharpness criteria for purposes of image reconstruction is discussed in terms of a probabilistic model. This model provides a general framework for understanding sharpness criteria and predicts that the accuracy of the phase compensation process is proportional to the number of discrete phase correcting elements.
