Very clever and I wonder how it will handle the most significant issue with Bayer type sensors, namely interpolation errors and colour aliasing.   The video suggest this is intended mainly for security cameras where low light sensitivity is important.  It may not be used at all for normal photography.

Panasonic invents non-Bayer sensor using diffraction actually
« Reply #3 on: March 31, 2013, 10:23:54 PM »

The article is a bit confusing with its talk of "deflectors": the mechanism is actually diffraction, using the fact that longer wave lengths (red, or red+green=yellow) are affected more than shorter ones (green+blue=cyan or blue).

There was another thread about this, linking earlier news stories, but I cannot find it for now, and do not mind a new discussion of a promising idea. It seems limited to very small "camera-phone sized" pixels, small enough for diffraction to be a strong effect, but maybe larger sensors could use a great many of these tiny pixels and bin the data on-chip.

P. S. I found the eariler thread: http://www.luminous-landscape.com/forum/index.php?topic=74893.0
which links to the original Panasonic press release.

Video was helpful.  Has been discussed in an earlier thread

It seems like a lot of work for a one-stop gain. 30+ seconds to open and color accuracy might be a bit dodgy.
