  • Patent number: 10409077
    Abstract: A head-up display includes a projector and an optical combiner configured to reflect light from the projector while allowing other wavelengths of light to pass through the optical combiner. The projector has two or more image sources, and two or more optical components, each of which is associated with a corresponding one of the image sources. In a typical implementation, the two or more optical components are closely situated to approximate an effective aperture that is larger than the actual aperture of either optical component. In such an implementation, since the actual aperture of each respective optical element is smaller than the larger effective aperture, it is generally much easier to correct for optical aberrations and the like, than it would be if a single optical element with a larger actual aperture were used.

  • Patent number: 10345600
    Abstract: A head-mounted display (HMD) presented herein comprises an electronic display, an optical assembly with a dynamic optical axis component (DOAC), an eye tracker and a controller. The electronic display is configured to emit image light. The eye tracker is configured to determine a gaze vector of a user wearing the HMD. The DOAC is positioned in front of the electronic display and refracts the image light received from the electronic display. The controller provides emission instructions to the DOAC to dynamically move an optical axis of the DOAC to align the optical axis with the determined gaze vector. The optical assembly directs the image light refracted by the DOAC to an eye box of the HMD corresponding to a location of an eye of the user. An optical error associated with the refracted image light directed to the eye box is reduced.
