摘要: An eye-tracking system is provided. An at least partially transparent visible light waveguide has a visible light display region configured to emit visible light to an eye of a user. A light source is configured to emit at least infrared (IR) light that travels along an IR light path to the eye of the user. A microelectromechanical system (MEMS) projector positioned in the IR light path directs the IR light. At least one diffractive input coupler on an input end of the IR light path downstream of the MEMS projector diffracts at least a portion of the IR light. At least one diffractive output coupler positioned in the IR light path downstream of the diffractive input coupler receives the IR light and directs the IR light toward the eye. At least one sensor is configured to receive the IR light after being reflected by the eye.

摘要: Methods for improving the manufacturing of optical gratings and surface relief grating structures are described. An optical grating may be formed by spin coating a liquid monomer solution that includes a solvent, a liquid monomer, and a nanoparticle filler with a higher refractive index than the liquid monomer on a substrate. The optical grating may be formed by pressing a mold that includes nanostructures on its surface into the liquid monomer to form gratings and then hardening the liquid monomer while the mold is held within the liquid monomer. After the mold has been pressed into the liquid monomer, two regions within the liquid monomer may be formed: a first region that includes the gratings and that does not include nanoparticles (or that includes less than a threshold number of nanoparticles) and a second region arranged below the gratings that includes nanoparticles.

摘要: A display system comprises an optical waveguide and a light engine. The light engine generates multiple input beams which form a virtual image. An incoupling grating of the waveguide couples each beam into an intermediate grating of the waveguide, in which that beam is guided onto multiple splitting regions. The intermediate grating splits that beam at the splitting regions to provide multiple substantially parallel versions of that beam. Those multiple versions are coupled into an exit grating of the waveguide, in which the multiple versions are guided onto multiple exit regions. The exit grating diffracts the multiple versions of that beam outwardly. The multiple input beams thus cause multiple exit beams to exit the waveguide which form a version of the virtual image. One or more surfaces of the intermediate grating comprise surface variations such that a visible banding effect is eliminated from the version of the virtual image.
