  • Patent number: 11754836
    Abstract: A projection augmented reality headset (ARHS), providing a wide field-of-view and an optimized eye relief. THE ARHS includes a projection having an imager and imaging optics which provides image light to a partially reflecting combiner. Further, the partially reflecting combiner configured to receive the image light, and is configured to re-direct the image light towards an eyebox, with an eye relief offset between the partially reflecting combiner and the eyebox. As such, the imaging optics include a combination of lens elements having symmetrical or free-form lens surfaces that are tilted and decentered to expand a field-of-view.
