In this work, we compare the performance of previously proposed ultra-miniature diffraction gratings with ideal lenses and zone plates of similar structural characteristics. The analysis aims at understanding the differences of designs utilizing non-focusing gratings and the potential benefits of their use in computational imaging systems.
