I saw this at a DSO* presentation ("Darpa's Darpa") back in ~2018. Hope they've gotten some early traction, that was some of the least wild crap that was being presented.

My company was pitching holographic cameras, and we weren't scifi enough. The investigator wanted to know if we could do hyperspectral 3D imaging from something the size of a sugar cube. ("Uh, no?" was our response.)
