This is serious stuff, but don't get too excited. It looks a lot like a
fourier optics phase contrast system. I suspect the wavefront masking
element is designed to be produced with tolerences less than 1/4 of the
wavelength of light, so it won't come cheap. Performance will be
strongly dependent on the precision of the other elements too.
The applications to date seem to focus on microscopy. I don't think that it is possible to do any kind of fourier optics (including phase contrast techniques) at infinity focus.
I had a brief look at the patents last week, and I agree. This is interesting, but for photographic application I have my doubts whether we will se any practical solutions. My guess is that you would have problems related to diffraction, focussing at infinity and contrast.
