Abstract

A novel approach is proposed for obtaining high resolution image of removing the optical aberrations by disturbing the optical wave-front phase and digital image processing. An optical random phase mask of the phase spectrum fluctuation corresponds to Kolmogorv distribution is placed between the exit pupil and image plane of optical system to make the optical aberration image blurred termed the intermediate image. The intermediate image acquired by digital detector is restored through the blind deconvolution algorithm base on maximum-likelihood estimation technique. The effect of optical aberrations on restoration image and superresolution performance of image was explored. As a demonstration to verify the utility of this method, the primary aberrations corresponding to the optical system are applied, and the image of removing the aberrations by a computer simulation and experiment is shown. The results suggest that the present method is well suited for improving the imaging quality of the optical system, and partly removing the diffraction effect of optical system on restoration image.
