Imaging properties of optical scanning holography and an aberration compensation filter.

We propose a numerical technique that analyses the imaging properties of optical scanning holography (OSH) constructed using real optical components in a real optical alignment situation. Using the proposing technique, we analyze the aberrations and the vulnerability of the OSH about the optical alignment. After that, we propose a digital filter that compensates the aberrations of the OSH. Finally, we show that the digital filter removes the aberrations of an experimentally recorded OSH.
