Abstract: Disclosed herein is a mixed illumination system including: a first light source; a second light source of different type than the first light source, where the wavelength an output of the second light source does not overlap with the wavelength of an output of the first light source; and a combiner which is configured to combine the output of the first light source and the second light source. The light from the first light source and the second light source are combined within the combiner into a combined beam.

Abstract: Disclosed herein is a head worn augmented reality display including a waveguide assembly including a first waveguide and a second waveguide; a first projector configured to output image containing light towards a first waveguide, where the image containing light is inputted into total internal reflection in the first waveguide and then outputted towards a user's first eye; a second projector configured to output image containing light towards a second waveguide, where the image containing light is inputted into total internal reflection in the second waveguide and then outputted towards a user's second eye. The first waveguide and the second waveguide are substantially transparent to light from the outside environment such that both the image containing light and light from the outside environment enters the user's eyes.

Abstract: The present disclosure relates to modular waveguide displays including: a modular frame; a waveguide lens attached to the modular frame, where the waveguide lens in configured to be attached to the modular frame to locate one or more waveguides within the waveguide lens in front of the modular frame; and an optical engine which is configured to be attached to the modular frame, wherein, when the optical engine is attached to the modular frame, the optical engine is configured to provide image containing information to a front side of the one or more waveguides. Advantageously, a modular waveguide display allows for customization by a user. The modular waveguide display is designed to operate without such components as the optical engine when such functionality is undesired to save weight and power. Also, modular waveguide displays allow for parallel development of components such as the waveguide lens and the optical engine.

Abstract: Methods and apparatus for eye-glow suppression in waveguide systems is disclosed herein. Some embodiments of the methods and the apparatus include a source of image modulated light; a waveguide having an eye-facing surface and an external surface facing the outside world; an input coupler for coupling the light into a total reflection internal path in the waveguide; at least one grating for providing beam expansion and extracting light from the waveguide towards an eyebox; a polymer grating structure comprising a modulation depth and a grating pitch. The modulation depth is greater than the grating pitch across at least a portion of the polymer grating structure. Advantageously, the polymer grating structure is configured to diffract light entering the waveguide from the outside world or stray light generated within the waveguide away from optical paths that are refracted through the external surface into the outside world.

Abstract: Systems and methods for real-time color correction of waveguide-based displays are disclosed herein. In some embodiments, a color correction system is included. The color correction system may include a light source, a detector, and a waveguide. The waveguide includes an input grating to inputting illumination light from the light source into the waveguide; an illumination grating for deflecting the illumination light towards an eye; a detector grating to input illumination light reflected off the eye into the waveguide; and an output grating for outputting the reflected illumination light from the waveguide into the detector.

Abstract: Methods and apparatus for eye-glow suppression in waveguide systems is disclosed herein. Some embodiments of the methods and the apparatus include a waveguide based display including a waveguide including an in-coupling optical element and an out-coupling optical element, where the in-coupling optical element is configured to in-couple image containing light and the out-coupling optical element is configured to out-couple the image counting light towards a user, where the waveguide comprises an outer surface and an inner surface opposite to the outer surface, and wherein the inner surface is closer to the user than the outer surface; and a partially light blocking layer above the outer surface of the waveguide opposite to the user, where the partially light blocking layer is configured to keep eye glow light from entering the environment outside the outer surface of the waveguide.
