Presumably, the aliasing would be reduced with newer MFDBs with higher resolution.
Hi Bill,
That would indeed help some, assuming the sensor array size stays the same
and the sampling gets denser (smaller sensel pitch for the same image magnification factor).
Part of the effects shown, the false color artifacts, can be solved by different demosaicing and/or moiré suppression afterwards, but the origin of the artifacts is exacerbated by the combination of 'large' sensels relative to the level of image detail and the lack of an OLPF (which boosts the MTF near Nyquist).
As an alternative cure one could consider using a longer focal length (which magnifies the detail and reduces the risk of aliasing), and the use of stitching for a restoration of the FOV (stitching for resolution enhancement, which also boosts the overall MTF). Diffraction, by using a second exposure with narrower aperture, can help with postprocessing of the problematic areas within the DOF zone (image magnification differences become too large outside of the DOF zone).
Cheers,
Bart
