Microsoft patents waveguide lenses with anti-reflective layers
Microsoft describes an optical component for display devices that uses a waveguide to carry light via total internal reflection. It adds layers of anti-reflective material and a nanometer-scale grating to help direct the light out of the surface.
In the filing’s own words
An optic comprises an optical waveguide, a series of anti-reflective laminae, and an exit grating. The waveguide supports total internal reflection of display light from the surface. The series of anti-reflective laminae are formed on the optical waveguide and arranged parallel to the surface. The exit grating is formed on the series of anti-reflective laminae. The exit grating includes a two-dimensional matrix of replicated, nanometer-scale features distributed parallel to the surface.
What exactly they claim (claim 1)
1. An optic comprising: an optical waveguide having a surface and supporting total internal reflection of display light from the surface; a series of anti-reflective laminae formed on the optical waveguide, arranged parallel to the surface; and an exit grating formed on the series of anti-reflective laminae, the exit grating including a two-dimensional matrix of replicated, nanometer-scale features distributed parallel to the surface.
