We investigate hybrid imaging systems consisting of a lens and a fast post-processing algorithm, where the lens is designed or co-designed with professional systems optical design software. Two approaches have been investigated: adapt the optimization criterion to the use of a unique deconvolution filter by requiring uniformity of the modulation transfer functions (MTF) over the field of view, or use piecewise-constant deconvolution to adapt the processing algorithm to spatial variations of the MTF in conventionally designed optical systems. By studying the evolution of the deconvolution performance across the field of view in systems optimized with these two approaches, we highlight that the optimal use of post-processing algorithm leads to lenses whose intrinsic performance varies little in the field of view, with however a significant amount of appropriate aperture aberrations but well suited to be post-processed.
