Microsoft may be hard at work making HoloLens and other AR/VR headsets a reality for Windows, but none of these devices really deal with holograms.
A true hologram requires a laser-generated 3D image floating in front of your vision to work. HoloLens uses two, 2D images projected onto flat glass to create the illusion of a 3D object. In Microsoft’s latest breakthrough, the image is generated right onto the lens itself to create a true holographic image in one eye.
Microsoft is also working on making holograms more comfortable to look at. They are currently hoping to make holographic displays that people could use without their corrective lenses. These holograms would be able to correct near- and far- sightedness as well as astigmatism. Microsoft’s current holographic display now take into account once inaccessible combinations form factor and field of view as well. Their most recent prototype is similar to sunglasses in form with a thin and transparent holographic optical element. It also allows for a 80 degree horizontal field of view.
