Different polynomial expressions for wavefront aberrations

摘要

The wavefront aberration is the difference between the real wavefront forming an image of an object point and a close reference sphere, described as an aberration function. This wavefront aberration function has been expressed by different authors as different polynomial families or polynomial series. This polynomial has their own characteristics and applications. The physical interpretation is customarily done in terms of Seidel, Zernike, Stephenson and many other aberrations. We will compare these different representations and will propose a new one.
