21 November 2007Holographic correction of an aberrated optical imaging system
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.
