Aberrations in high aperture conventional and confocal imaging systems

CJ Sheppard
AbstractAn appropriate form for the expansion of an aberration function for an optical system of high numerical aperture is considered. The effects on the defocus signal of a confocal imaging system of aberrations, high aperture, finite Fresnel number, system configuration, and surface tilt are discussed.
