Abstract
Based on the principle of holography, a holographic experimental system for the correction of an aberrated optical imaging system with a low quality glass spherical mirror in diameter of 200mm is set up in this paper. An image hologram of the aberration mirror is recorded and reconstructed by the wave with the same wavelength as in recording from a distant object. By testing the interferogram of the reconstructed reference beam and the original reference beam and comparing the images of a pin-hole in diameter of 25μm before and after correction, the effect of correction is analyzed. The experimental results show that with the image hologram in the optical imaging system, almost all the aberrations of the spherical mirror and the optical imaging system can be corrected and near diffraction-limited performance can be obtained.
