This page computes and plots variuos characteristics of the Zernike polynominals. Optical system is assumed to be circular in shape. x p and y p are the normalized exit pupil coordinates, where the x p axis defines the sagittal plane and the y p axis defines the meridional plane. Each aberration is specified using two subscripts n ...
