Analysis of Geometric Wavefront Sensing

Abstract

The objective behind all wavefront sensors is to form an estimate of the phase aberrations in the instrument. In practice the wavefront in the aperture is described as the sum of orthonormal basis functions, typically the Zernike polynomials. The coefficients of the basis functions are usually assembled as a coefficient vector [a], which completely describes the phase aberration of the wavefront.
