This study introduces methods for converting between different wavefront expansion basis functions, like Zernike polynomials and Fourier series. This facilitates accurate representation of ocular aberrations and atmospheric turbulence effects.

Area of Science:

  • Optics and Photonics
  • Astronomy and Astrophysics

Purpose of the Study:

  • To provide a general framework for converting coefficients between arbitrary wavefront expansion basis functions.
  • To derive conversion matrices for commonly used basis sets: Zernike polynomials, Fourier series, and Taylor monomials.
  • To demonstrate the practical application of these conversions with examples.

Main Methods:

  • Derivation of general conversion formulas for basis function coefficients.
