Defocus impact analysis on telescope wavefront reconstruction by scattering spot with parametric optimization technique

Subject of Research. Wavefront reconstruction by the known scattering spot intensity with parametric optimization is presented. The Zernike polynomial coefficients of the wave function expansion as optimization parameters are used. The known defocus impact is performed on the method convergence. M...
