A lot of the technology billed as holographic, well, isn't. Not even HoloLens. Real holography requires a laser-generated 3D image, and it's no mean feat to stuff that into something you can comfortably wear. Microsoft just made some important progress, however. Its researchers have developed a true, near-eye holographic whose optics can fit inside a regular pair of glasses. The mirrors and the liquid crystal on silicon needed to achieve the effect sit inside the frame -- it's only the electronics that have to stay outside. While this extra-compact size would normally result in an unusable picture, corrections in the holographic projector make it easy to read details down to individual pixels.
