Abstract

We present a comprehensive study of the effect of detector sampling on wavefront-coded systems. Two important results are obtained: the spurious response ratios are reduced in wavefront-coded systems with a cubic phase mask and detector sampling does not compromise the restoration of wavefront-coded images with extended depth of field. Rigorous computer simulation of sampled wavefront-coded images shows an increased signal-to-aliased-noise ratio of up to 16% for a cubic phase mask with a 5?. © 2009 IOP Publishing Ltd.
