AR and VR headsets of the future could have clearer, lighter, and wafer thin lenses, thanks to a new manufacturing process that uses nanotechnology to not only shrink the thickness of the lens, but also correct for the sort of color distortions common to the lenses currently used in VR headsets.
the researchers say they’ve refined their design, allowing for arbitrarily adjustments to the transmission speed of light passing through different points on the lens. By modulating the transmission speed, the light can be made to arrive simultaneously at the focal point, resulting in a sharper image
We put the faster-transmitting nanostructures at the edges of the lens, so light travels through them faster than in those in the middle. This effectively helps the light from the meta-lens edges catch up with light at the center, so that all the rays focus together.
Though nanotechnology sounds exotic (and expensive), the researchers say that this approach could lead to better and cheaper lenses, and specifically suggest head mounted displays as one potential applicationhttps://www.roadtovr.com/new-flat-lens-give-vr-headsets-better-image-quality-making-lighter-compact/
