5 March 2008High resolution imaging by random disturbing wave front phase
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.
