Title: Estimating field-dependent nodal aberration theory coefficients from Zernike full-field displays by utilizing eighth-order astigmatism

Journal Article · · Journal of the Optical Society of America. A, Optics, Image Science, and Vision

When using freeform surfaces in optical design, the field dependence of the aberrations can become quite complex and understanding these aberrations facilitates the design process. Here, we calculate the field dependence of low-order Zernike astigmatism (Z5/6) up to 8th order in Nodal Aberration Theory (NAT). Expansion of NAT astigmatism terms to 8th order facilitates a more accurate fit to the Zernike astigmatism data. We then show how this estimated field dependence can be used to quantitatively analyze a freeform telescope design. Lastly, this analysis tool adds to the optical designer’s arsenal when up against the challenge of designing with freeform optics.
