Abstract

The mechanics and method of correction of an aberration optical imaging system by means of holographic technology were described in this paper. An experimental system for the correction of aberrations of an optical system with a low quality spherical mirror in 500mm-diameter for the imaging of finite objects was established. The correction effect was tested by comparing the interferograms and images obtained before and after corrections. Experiment results showed diffraction-limited performance of the system and residual aberration was ~ λ/8.
