Submitted article extremely light on details, and conflates the researcher's incremental improvements in holography with long established techniques such as holographic stereograms.

And no, we aren't any closer to virtual 3D objects in free space, no matter what the Economist says. Physics.
- jcl 9y agoReminds me a bit of the "caustic design" papers in recent SIGGRAPHs in that they're both optimizing a lens's shape so that it produces a particular output lightfield -- although the hologram needs to incorporate diffraction and produce a much more constrained lightfield.
