The dynamic range of a Shack-Hartmann sensor is normally limited by the fact that the foci can leave their subapertures and so a definite attachment of the foci to their subapertures is difficult. One method for solving this problem is to give the focal spots a kind of label to identify them even if they leave their subaperture. We describe how the dynamic range of a Shack-Hartmann sensor can be expanded by using lenses with well-defined astigmatism. We also derive a relation between the spot displacements and the partial derivatives of the wavefront for large wavefront slopes.
