There are even and odd Zernike polynomials. The even Zernike polynomials are defined as (even function over the azimuthal angle ), and the odd Zernike polynomials are defined as (odd function over the azimuthal angle ) where m and n are nonnegative integers with n ≥ m ≥ 0 (m = 0 for even Zernike polynomials), is the azimuthal angle, ρ is the radial distance , and are the radial polynomials defined below. Zernike polynomials have the property of being limited to a range of …
