Doubling HoloLens Field of View

The main issue with the Microsoft HoloLens is its limited field of view, dictated by the physics of the technology used. Microsoft writes that to enable the use of internal reflection in the waveguide they are forced to limit themselves to a range of exit angles of around 35 degrees, which dictates the subsequent field of view of the hologram as seen by the user.


They have however developed a clever technique to get around this limitation, by splitting the image sent down the waveguide into two elements, which then has 2 separate exits, and while each will be limited to 35 degrees, the subsequent final image seen by the user can span up to 70 degrees. They demonstrated the technology in actual hardware and that the solution is more than theoretical.
