WebThe aberrations of imaging systems with uniformly illuminated annular pupils are discussed in terms of a complete set of polynomials that are orthogonal over an annular region. These polynomials, which we call Zernike annular polynomials, are similar to the Zernike circle polynomials and reduce to them as the annulus approaches the full circle. The Zernike … WebResults: Zernike vector analysis showed prominent vertical coma with an inferior slow pattern, with mean axes of 82.5 degrees or 91.0 degrees in the patients with keratoconus or keratoconus suspect, respectively. The mean axes of trefoil in patients with keratoconus (93.8 degrees ) and keratoconus suspect (100.6 degrees ) differed from that in ...
WebComparison of Zernike coefficients. Zernike polynomials are useful in describing ocular aberrations. The Zernike coefficients of metropic eyes, corrected-amblyopic group, refractory amblyopic group and amblyopic group were compared and the differences between Z 2 0, Z 2 2, and Z 3-1 were found to be statistically significant (P <0.05).
