title = "Diffraction effects for interferometric measurements due to imaging aberrations",
abstract = "Aspheric surfaces are often measured using interferometers with null correctors. The null corrector creates a wavefront that matches the surface under test, but also introduces imaging aberrations, such as mapping distortion and field curvature. These imaging aberrations cause high frequency features in the surface under test to be filtered out and create artifacts at edges. We provide a concise methodology for analyzing these effects using field curvatures, and showing how they couple with diffraction as represented by the Talbot effect and Fresnel edge diffraction.",
