Abstract

Based on an analytical analysis of the optical transfer function in an optical system with wavefront coding, specifically with a cubic phase mask in the aperture stop, we explain that such systems have image artefacts in the restored images and that these are manifested as replication artefacts. To remove image artefacts we propose to store a set of defocused point spread functions such that a single defocused image can be restored to a set of images, wherein one of them is without image artefacts. The image without image artefacts is determined with a new metric which we define in the wavelet domain.
