It also covers holographic display:
At the receiving end, a PC with three commercial graphics processing units -- GPUs -- computes the diffraction patterns.
The one component of the researchers’ experimental system that can’t be bought at an electronics store for a couple hundred dollars is the holographic display itself. It’s the result of decades of research that began with MIT’s Stephen Benton, who built the first holographic video display in the late 1980s. ... The current project uses a display known as the Mark-II, a successor to Benton’s original display that both Benton’s and Bove’s groups helped design.
