摘要： An illumination waveguide is described having a top surface and a bottom surface, and a plurality of reflective elements within the waveguide, the reflective elements at an angle to the top surface of the waveguide, the reflective elements providing one or more of: an in-coupler, an out-coupler, and an extender to the waveguide. The illumination waveguide is configured such that light from the waveguide is directed to a spatial light modulator, and the modulated light is directed through the waveguide to a user.

摘要： A relative position based eye tracking system includes a light source to illuminate a portion of the eye and an optical sensor to capture a sequence of samples of the portion of the eye. The system further includes a sample comparator to compare two samples and a relative position calculator to calculate a change in the position of the eye based on data from the sample comparator.

摘要： A system comprising an illumination system to direct light from one or more light sources to a limiting output pupil of a projection optomechanical system, a liquid crystal on silicon display panel (LCOS) to modulate the light from the projection optomechanical system and to direct the modulated light back toward the projection optomechanical system, and an in-coupler to a combiner waveguide to receive the modulated light from the LCOS, after it passes through the projection optomechanical system. The system in one embodiment is designed so that the light that passes through the projection optomechanical system from the illumination system lands on the LCOS within the limiting output pupil of the projection optomechanical system.

摘要： A system including a steerable mirror, a waveguide, first optics, intermediate optics, and final optics. The system includes a first light path for a foveal image element, the first light path including the first optics, the steerable mirror to steer a position of the foveal image element to a particular orientation, intermediate optics, and the final optics to direct the foveal image element to an in-coupling region of the waveguide. The system further includes a second light path for a field image element, the second light path including final optics.
