Web8 aug. 2024 · Wavefront aberrations can appear complex to understand, however when broken down to core concepts a single wavefront is nothing more than a three dimensional shape that is frozen in time. The complexity comes down to how to describe the shape, and you already do this to some degree in your everyday practice! Web16 jan. 2024 · The detected wavefront of the S-H wavefront sensor is described in terms of Zernike coefficients. The Zernike coefficients are easy to be rotated since all the Zernike polynomials are circularly symmetric or orthogonal in pairs. Rotation of orthogonal polynomial pairs is performed by multiplying a rotation matrix with their coefficients.
