Abstract

Hartmann wavefront sensors rely on an exact correlation between a transverse ray aberration measurement in the focal plane and the sampling hole position in the pupil identifying that ray. lf this relationship breaks down, the reconstructed wavefronts will not correspond to the actual incident wavefronts. This occurs if rays yielding certain transverse errors are misidentified, e.g., if sampling is in a plane not conjugate to the pupil. A case study is made of the SHAPE wavefront sensor in which such ray misidentification can arise.
