Abstract

Abstract Computer simulation has been used to enhancement the quality of astronomical image formed by a singlet eyepiece. And by examining the Zernike coefficient values of an aberrated image wave-front for this system and utilizing them to show the effect on image quality. The aim of this research is to measure Zernike coefficients and added them to the lens surfaces of eyepieces, in order to avoid the atmospheric turbulence .The simulations carried out with ZEMAX-EE Optical Design Program (Version 2009) in three different wave length (0.486133, 0.587562, 0.656273). The results show an enhancement on image quality by means of FFT MTF, OPD Fan, RMS field and FFT PSF.
