Paper Abstract

Conventional modal compensation using Zernike polynomial expansion by means of Hartmann-Shack wavefront sensors is discussed. Cross-talk problems of Zernike coefficients have been found to be serious, especially for large sub-aperture configurations. A proposal for use of a modified Hartmann-Shack wavefront sensor and iterative wavefront reconstruction is presented and a comparison is made between conventional and proposed methods.
