Paper Abstract

We analyze the performances of the most known phase filter design (the cubic phase plate) in wavefront coding systems with respect to on- and off-axis imaging. To this end, the PSF will be calculated at different off-axis positions and the contribution of coma and astigmatism aberration terms to its spatial variation will be evaluated. The study will include the subsequent digital image processing procedure as well, so that a clear idea of the overall system performance will be drawn.
